Replacing a Failed Window Regulator: 7 Solid Picks
The Dorman 741-874 Power Window Regulator with Motor is our top overall pick for its documented fitment and metal reinforced pulleys. The ACDelco Professional Power Window Regulator suits owners who want a factory equivalent part, and the ECCPP Power Window Regulator is the sensible budget replacement.
When a window rattles down inside the door and will not come back up, the regulator is usually the failed part rather than the motor. The Dorman 741-874, ACDelco Professional Power Window Regulator and ECCPP Power Window Regulator lead this ranking on build quality and fitment confidence.
This is a tricky part to buy because a single vehicle can take four different regulators depending on door, trim and whether the mirror is heated, and a wrong order means the door comes apart twice. We compared cable routing, pulley materials, whether a motor is included, warranty terms and what owners report about how long the replacement lasted.
What we recommend
Dorman 741-874 Power Window Regulator with Motor
Dorman supplies this as a complete assembly with the motor already fitted, so the job becomes a single swap rather than a transfer of parts. The pulleys are reinforced rather than plain plastic, which addresses the exact failure that kills most original regulators. Owners report the cable tension arrives correct out of the box, which saves the most frustrating part of the install.
Pros
- Motor included so no transfer needed
- Reinforced pulleys address the common failure
- Arrives correctly tensioned
Cons
- Costs more than a regulator only part
- Fitment must be verified carefully before ordering
ACDelco Professional Power Window Regulator with Motor
ACDelco Professional parts are built to original equipment specifications, which shows in the bracket geometry and connector fit. For General Motors vehicles in particular, the plug matches without adapters and the mounting holes line up first time. It is the pick for anyone who wants the replacement to behave exactly like the original part did when new.
Pros
- Bracket geometry matches factory
- Connector plugs straight in
- Consistent quality control
Cons
- Narrower vehicle coverage than aftermarket brands
- Premium pricing for the badge
Cardone Select Power Window Regulator
Cardone Select is a new part rather than a remanufactured one, and the catalogue reaches back to vehicles that most brands have dropped. Cables are pre stretched at the factory so they do not slacken in the first few cycles. Based on specifications it is the strongest option for anyone keeping an older car on the road.
Pros
- Covers vehicles other brands have dropped
- Pre stretched cables resist early slack
- Choice of with or without motor
Cons
- Instructions are minimal
- Some listings ship without the motor
TRQ Power Window Regulator with Motor
TRQ backs its regulators with an unusually long warranty, which matters in a category where the second failure is the one that really annoys people. The assemblies ship with the motor attached and the cable already routed. Owners report the packaging protects the cable loops well, which prevents the tangles that plague cheaper shipments.
Pros
- Long warranty for the category
- Ships well protected
- Motor included
Cons
- Fewer applications than Dorman
- Motor is a little slower than factory
ECCPP Power Window Regulator
ECCPP covers a broad range of common vehicles at the lowest outlay in this group, and the basic construction is sound for a part that will spend its life inside a dry door. Cable ends are crimped rather than moulded. It is a reasonable choice for a vehicle you plan to keep only a few more years.
Pros
- Lowest outlay of the group
- Wide coverage of common models
- Motor included on most listings
Cons
- Plastic pulleys rather than reinforced
- Occasional need to adjust cable tension on fitting
AUTOSAVER88 Power Window Regulator with Motor
AUTOSAVER88 ships a complete assembly with the motor bolted on and the harness pigtail attached, so most installs come down to four bolts and a connector. The bracket stampings are thicker than the price suggests. Owners report the units are quiet when new, though a few note more motor noise than the factory part after a year.
Pros
- Genuinely bolt in on most applications
- Thicker brackets than expected
- Quiet operation when new
Cons
- Motor noise can increase over time
- Fitment listings need double checking
SCITOO Power Window Regulator
SCITOO sells many applications as matched pairs, which is genuinely useful because rear regulators tend to fail within months of each other on the same car. Construction is basic but adequate, with steel guide rails and standard plastic pulleys. It is a practical way to refresh both rear doors in one job.
Pros
- Matched pairs available for rear doors
- Steel guide rails
- Straightforward cable routing
Cons
- Plastic pulleys are the weak point
- Instructions not included

How to choose
Confirm the regulator, not the motor, is the failure If the motor hums or clicks but the glass does not move, the cable has almost certainly snapped or jumped its pulley. If nothing happens at all and the switch and fuse check out, the motor is the suspect. Replacing the complete assembly removes the guesswork entirely, which is why regulator plus motor units are the most common choice for a repair meant to last.
Order by door, side and trim level One vehicle can list four different regulators: front left, front right, rear left and rear right, and some trims add a different bracket for one touch operation. Have the vehicle identification number to hand and match the part against the listed fitment before ordering. Owners report that the most common failed repair is a correct quality part bought for the wrong door.
Pulleys and cable ends predict how long it lasts The original part usually fails at a plastic pulley or a frayed cable end, not at the motor. Reinforced pulleys and pre stretched cables, as used on the Dorman and Cardone assemblies, address that directly. If a listing says nothing about either, assume standard plastic components and expect a shorter service life.
Plan the door card removal before you start Most of the job is getting the trim panel and vapour barrier off without breaking clips, and getting them back on without rattles. A plastic trim tool set, a spare set of clips and a torx driver cover the majority of vehicles. Keep the vapour barrier intact or reseal it properly, since a torn barrier leads to damp carpets and electrical faults later.
Frequently asked questions
How do I know if my window regulator is bad?
The classic sign is a bang or clunk followed by the glass dropping into the door, sometimes with the motor still humming. A window that moves crookedly, binds halfway or comes down but not up also points to a regulator problem rather than a switch or fuse.
Should I replace the motor at the same time?
It is usually worth it. Buying the regulator and motor as one assembly means the door only comes apart once, and the labour is the expensive part of this job whether you do it yourself or not.
Are aftermarket window regulators any good?
The better aftermarket brands address the original weak points, particularly plastic pulleys, by using reinforced components. Dorman and Cardone in particular design around known failure modes, which is why they rank highly here.
Can I replace a window regulator myself?
Most people with basic tools can. The work is removing the door trim panel and vapour barrier, unbolting the glass from the carrier, then swapping the regulator. Allow a couple of hours for a first attempt and take care with the trim clips.
Why did my new regulator fail quickly?
The usual causes are incorrect cable tension on installation, a bent or dirty window channel binding the glass, or a felt run channel that has hardened. Fixing the channel is what stops the next regulator from being loaded the same way.
What is the difference between cable and scissor regulators?
Cable regulators use a drum and cable to raise a carrier along a rail and are used on most modern vehicles. Scissor regulators use a pivoting arm assembly and appear on older designs. They are not interchangeable, so buy the type your door was built for.
Do these parts come with a warranty?
Most do, and terms vary widely. TRQ offers an unusually long warranty in this group, while ACDelco Professional and Dorman both provide standard coverage. Keep the receipt, since a claim normally needs proof of purchase.
Do I need to reprogram the window after fitting?
Some vehicles with one touch or auto up need the window position relearned, which is typically done by holding the switch up for a few seconds after the window reaches the top. Check the owner manual for the exact procedure.
The verdict
The Dorman 741-874 Power Window Regulator with Motor is the pick we would fit ourselves, because reinforced pulleys and a pre tensioned cable address exactly what fails on the original part. Choose the ACDelco Professional unit if you want factory equivalent fit and finish, or the ECCPP regulator if the vehicle only needs to keep going a few more years.
