Rear driver-side window regulator replacement addresses dropped glass, crooked movement, grinding or a window that will not travel on 2000–2006 Chevrolet Tahoe and GMC Yukon, and 2002–2006 Cadillac Escalade. There is no dedicated generic OBD-II P-code that identifies a broken regulator. Any body or door-module codes require their own circuit diagnosis; neither symptoms nor a code alone proves that the regulator and motor need replacement.
This guide covers the left rear passenger door of the standard-length SUVs listed below. The lifting assembly includes its motor. Door geometry, side and connector are the purchasing checks that matter here; sharing an engine with another GM vehicle does not establish compatibility. Exclude Yukon XL, Escalade ESV and EXT, Suburban and pickup applications from this guide.
Intermediate; glass support and trim work
1–2 hours for one rear door; allow longer for diagnosis
$45–$100 for one aftermarket motor/regulator assembly
Featured replacement
A-Premium WR0098 is one electric rear-left window regulator with a two-terminal motor. ASIN: B074YF5LWN. The manufacturer cross-references 15135972, 19260050 and 748-228. Check the original mechanism and electrical plug before purchase. The package is a single-door assembly; replacement glass, door switches and trim are separate items. Confirm any loose fasteners or pads needed for your installation rather than assuming they are included.

Vehicle compatibility
| Make / model | Years | Engine information | Door and configuration |
|---|---|---|---|
| Chevrolet Tahoe | 2000–2006 | Listed V8 4.8L / 5.3L applications; trim/year combinations vary | Standard-length SUV, rear left power window; match original part |
| GMC Yukon | 2000–2006 | Listed V8 4.8L / 5.3L applications | Standard Yukon, not Yukon XL |
| GMC Yukon Denali | 2001–2006 | Listed V8 6.0L | Standard-length Denali, not XL |
| Cadillac Escalade | 2002–2005 (5.3L); 2002–2006 (6.0L) | Listed V8 5.3L / 6.0L | Standard Escalade, not ESV or EXT |
These are catalog applications, not a promise that every trim in a continuous year range uses the same unit. Engine entries describe listed vehicles, not an engine-dependent installation. On a 2000 vehicle especially, match the actual door design and OE interchange. Transmission and drivetrain are not the selection criteria stated for this assembly. Use the seller’s vehicle selector and compare mounting points, connector and glass attachment before dismantling.
Symptoms, fault codes and diagnosis
First note whether the window fails from both the driver’s master switch and the rear-door switch. Check the window lockout setting. If one switch operates it normally, investigate the other switch and its circuit before ordering a regulator. If several windows fail together, a shared power or control fault is more likely than several simultaneous broken lifting mechanisms.
- Motor runs but glass stays still: inspect the lifting mechanism and glass attachment.
- Glass drops, tilts or crunches: stop cycling it and secure it before inspection.
- No motor sound: check fuse/circuit protection, connectors, door-jamb wiring and motor supply.
- Slow or tight travel: inspect run channels and alignment as well as the motor.
A circuit test should establish correct supply and ground under load using the vehicle wiring diagram. Do not bridge unidentified pins or apply an unfused battery lead. If you lack the diagram or electrical-test experience, have that diagnosis performed before opening the replacement package. A new motor will not repair a broken wire, and a new regulator can be damaged by a binding pane.
Code interpretation: an engine-code reader is not a mechanical window test. There is no universal manufacturer B-code that proves WR0098 is needed. Record any available body-module codes and diagnose their exact definitions for the model year. Do not clear unrelated engine faults to judge whether the window repair succeeded.
Tools, parts and supplies
The table supplies one practical product choice for each task. Check your existing tools first. Seven- and ten-millimeter sockets are used in the illustrated Tahoe rear-door procedure; previous repairs and trim variations can change the fasteners you find.
| Tool or Supply | Exact Product | Product Link | Purpose and Selection Check |
|---|---|---|---|
| Sockets, ratchet and extensions | GEARWRENCH 80300P, 51-piece 1/4-inch-drive SAE/metric 6-point set | View sockets, ratchet and extensions | Includes 7 mm and 10 mm sockets for the illustrated door. Use hand tools; match each fastener before turning. |
| Screwdrivers and bits | TEKTON 2841 Everybit 135-piece ratchet screwdriver and bit set | View screwdrivers and bits | Slotted and precision drivers for trim and connector latches. Release the latch; never pull the wiring. |
| Trim tools | GOOACC 5-piece nylon trim removal kit, red | View trim tools | For bezels and trim edges after screws are removed. The door panel lifts off hooks; do not pull it outward by force. |
| Inch-pound torque wrench | LEXIVON LX-181, 1/4-inch drive, 20–200 in-lb | View inch-pound torque wrench | Compatible with the socket drive above and the 80 in-lb setting. Measures clockwise tightening. Tool range is not a torque specification. |
| Temporary glass-support tape | ScotchBlue Original 2090-48SC6, 1.88-inch × 60-yard rolls, six-pack | View temporary glass-support tape | Usually one roll is ample. Use several long strips over the upper frame on clean, dry surfaces, with a helper supporting the glass. Not a driving repair. |
| Long-nose pliers — conditional | IRWIN Vise-Grip 2078216, 6-inch long-nose pliers | View long-nose pliers | For accessible retaining tabs or clips. Check reach before choosing; do not squeeze the glass or cut loaded regulator cables. |
| Eye protection | DEWALT DPG82-11 Concealer clear anti-fog goggles, one pair | View eye protection | Wear while removing trim and handling the assembly. Check fit over prescription glasses if applicable. |
| Work gloves | Mechanix Wear FastFit, black, large, MFF-05-010 | View work gloves | Select the correct hand size. Abrasion protection at door edges; these do not make shattered glass safe to handle. |
Condition-dependent materials: clean soft cloths, replacement panel clips, water-deflector material and resealing adhesive may be needed. Match clips and sealer to the original door; they are not universal kits. Retain sound original fasteners in labeled positions and replace damaged hardware with the correct length and grade. A new pane or damaged glass channel requires a separate, application-matched part.
DIY versus professional cost
| Cost element | DIY planning allowance | Shop planning allowance |
|---|---|---|
| One regulator with motor | $45–$100 | $80–$200 |
| Small clips / consumables | $10–$30 | $10–$30 |
| Labor | Your time; roughly 1–2 hours | $120–$300 |
| Total with tools already owned | $55–$130 | $210–$530 |
| Tools bought for this job | Add about $120–$250 if starting from scratch | Normally covered by labor charge |
These are editorial budgeting estimates, not live listing prices, flat-rate labor times or guaranteed quotes. Tax, shipping, electrical fault tracing, replacement glass and door damage are excluded. Ask a shop to separate diagnosis, parts and labor so you can compare the same scope. Paying for a reliable diagnosis can be less expensive than installing a part that does not address the cause.
Step-by-step replacement overview
- Plan the work. Confirm left-rear fitment and compare the connector. Photograph cable and wiring routes. Arrange a helper and protect the door trim.
- Secure the glass and isolate power. If safe movement is possible, position the pane for attachment access. Switch off and disconnect the negative battery cable. Support the pane before releasing any attachment.
- Remove trim carefully. On the illustrated Tahoe, release lock/handle covers and the 7 mm screws, then lift the panel off its hooks. Unplug the switch. Remove the handle/rod connection and speaker as needed to reach the mechanism; preserve the water deflector.
- Free the glass attachment. With the pane securely held, loosen the two clamp fasteners. Separate the carrier without levering against the glass edge. Raise and secure the pane with multiple tape strips and a helper.
- Remove the module. Disconnect the motor, release harness retainers and remove the regulator mounting fasteners. Support the unit and withdraw it through the opening. Do not cut loaded cables.
- Compare and fit. Check rails, connector and attachment positions against the removed assembly. Fit all mountings loosely first, without bending the rail or trapping wires. Restore any bracket locating tabs according to the replacement instructions.
- Align and tighten. The linked GM Tahoe/Yukon/Escalade module procedure specifies 9 N·m, approximately 80 in-lb, for both regulator mounting and glass-clamp bolts. Seat the glass squarely before tightening. Use replacement-specific instructions if its clamp design differs; never apply this value to trim screws.
- Test with the opening clear. Reconnect the motor and switch, remove temporary supports only after the pane is secured, then restore power. Start with short movements and continue through full travel if smooth. Stop for tipping, binding or cable noise.
- Reseal and reassemble. Isolate power again. Refit the water deflector, speaker, handle rod and panel. Keep drain paths open and wires clear. Reconnect power and check both switches, lockout, latch, lock and speaker.
Do not hold the switch continuously against a stalled window. If the glass will not release from its carrier without force, or cannot be held securely, stop and obtain glass-service assistance. Avoid impact tools on the clamps. Finish by checking that the door closes normally and the pane stays seated without rattling; tape is not a roadworthy substitute for a repaired attachment.

Common mistakes
- Ordering an XL/ESV, front-door or right-side assembly because the vehicle names look similar.
- Skipping the lockout and switch checks.
- Releasing glass before providing independent support.
- Using foot-pounds when the intended setting is inch-pounds.
- Tearing the water deflector or sealing over door drains.
- Pinching wiring behind the regulator or leaving the handle rod unlocked.
Frequently asked questions
Does this fit Yukon XL or Escalade ESV?
No. The manufacturer explicitly excludes those longer-body models. Their rear doors must be matched separately.
Must both rear regulators be replaced?
No. Diagnose each side. This listing and the estimates cover one rear-left assembly.
Can I reuse the old motor?
The featured assembly already includes a motor. Motor transfer belongs to a regulator-only installation and is unnecessary here.
Why does the window work from only one switch?
That points toward the switch/control path and merits diagnosis before mechanical replacement. Verify the rear-window lockout first.
Will replacing it clear an engine fault code?
No direct relationship should be assumed. Diagnose engine/emissions codes separately from this door mechanism.
Can a first-time DIY mechanic do this?
The work is manageable for someone comfortable removing trim and safely supporting glass. A helper, careful fastener control and an inch-pound torque wrench matter more than rushing. Broken glass or uncertain wiring is a reason to use professional help.
