Both Regulator and Motor: $150-$1,100+, Parts & Labor
On a vehicle with power windows, inside each door is a window regulator, the mechanical part that moves the window up and down, and a small electric window motor, which operates the regulator. If none of the power windows work, it could be a blown fuse or other problem in the vehicle's electrical system. If only one window is malfunctioning, the problem could be the regulator, the motor, or both.
Typical costs:
Opening up the door panel to diagnose the problem (and possibly simply clean out dirt and debris so a clogged window moves more freely) can cost $50-$200 or more, depending on local rates, the make and model of vehicle, and whether the work is done by an independent or chain repair shop, or a dealership (typically the most expensive).
For example, San Jose Auto Repair[1] in California estimates that opening and inspecting the door panel to diagnose the problem typically costs $49-$99; if additional repairs are needed, the diagnostic fee is applied toward the total cost.
Replacing a window regulator can cost $50-$550 for just the part, depending on make and model of vehicle , and whether the is produced by the vehicle manufacturer (called OEM) or another company (called aftermarket); 1.5-3 hours of labor at $50-$120 an hour brings the total up to $100-$900 or more, depending on local rates and the make and model of vehicle.
Replacing a window motor can cost $40-$300 for just the part, depending on make and model of vehicle and if the part is OEM or aftermarket; 1.5-3 hours of labor brings total costs to about $150-$900 or more.
If both the window regulator and motor are replaced (sometimes a good preventive move, even if only one is broken), the combined parts can cost $50-$850 or more, depending on make and model of vehicle and if the parts are OEM or aftermarket. For example, AutoPartsWarehouse charges $49-$107 for an aftermarket regulator and motor combination for a 2008 Honda Accord[2] . Labor of 1.5-3 hours brings total costs (parts and labor) to $150-$1,100.
Determining why a power window doesn't work and then replacing the regulator or window motor typically requires opening up the door panel, and removing the window glass. Mechanic Scotty Kilmer provides a video demonstration of removing a door panel[3] .
1A Auto Parts has a video series demonstrating how to replace a window regulator[4] depending on the year, make and model of vehicle, and whether it's a front or rear window.
AutoMD provides how-to instructions and a video demonstration[5] for replacing a power window motor.
Additional costs:
In many states there may be a core charge[6] of $20-$60 for the window motor; this is a recycling fee, similar to the fees on plastic bottles, and does not have to be paid (or will be refunded) if the old part is exchanged for the new one.
Discounts:
AutoMD estimates that do-it-yourself replacement of a window regulator[7] or window motor[8] each takes about 1.8 hours, while replacing both the window regulator and motor[9] takes about 2.1 hours. AutoMD rates all three projects as moderately complex; however, all three projects are rated as moderately complex. However, a Ford Expedition owner[10] reports being injured by the coil spring under the window motor, so read and follow all safety precautions carefully.
Shopping for power window repair:
A power window can be repaired by a car dealership, an independent repair shop, an automotive glass service, a car audio specialist (they're experienced at working inside car doors) or car-repair chains like Pep Boys[11] or Sears[12] . Both the National Institute for Automotive Service Excellence[13] and the International Automotive Technicians Network[14] provide a searchable directory of repair shops.

Motor died while window was in down position. Removed body panel, pulled back plastic vapor barrier, loosened and removed bolts for window regulator, all cables checked out fine. Tested switch and found voltage going to the motor, so deduced it wasn’t switch. Ordered new passenger side motor through Amazon. One day shipping, installed the next day, put everything back in reverse order. Easy Peasy. Saved over $750 according to what my local mechanic was going to charge me. Watch videos on YouTube if you need to, but not much to this from engineering standpoint.
Replace opposite side at a shop 3 years ago cost me $325. Opposite window I said “no way”. You tubed it. Bought the motor and regulator on amazon for $50 and did it myself in an hour and a half. Don’t let these shops rob u. This was a pretty simple job by watching the video.
Bought regulator (motor & cables) from Advance auto for $79 with online coupon. First one was all kinked up and looked like someone tried to replace it themselves and couldn't do it. Got a second one no problem to exchange, installed in about 3 hrs. I can see why the first guy returned it. I took a lot of time to finagle the new one in, the cables and rails have to be placed just right in order to get it in the door cavity. I've worked on factory machines all my life, so having this mechanical aptitude helped. It's not a job for the faint. Also, taking out the motor mounts was a pain. Bolts into rubber grommets. Had to have a razor blade on the back while screwing out bolts to cut the grommets. They were turning with the bolt. Over all, happy I did it myself and saved big bucks.
Broken regulator motor in my 2001 Honda Accord; asked the local dealership and was quoted 191.63 for Labor and 253.17 for Parts (Total: 444.80). Asked Youtube instead; after watching a couple of videos, it was easy (I have no automotive background; changed my oil once, that's about it) to take apart the door assembly and remove the regulator and motor. When I saw it really wasn't going to just patch back together, I found the part on Amazon.com for $54 and paid another $6 to over-night it, which was sooner than the dealership could get the manufacturer's shipped in. Installed it with no hassles the next day and it works like a charm. If you can watch a youtube video and use a wrench, you can do this yourself; on a Honda Accord at least.
Cable to the power window regulator snapped. Ordered new assembly online. Had to drill out old large rivets to take old assembly out, and install new assembly with new nuts, bolts and washers. Not fun, took a very long time to drill out and remove the factory rivets. Job better left to professionals. :) On the positive side, I saved money and if it ever happens again, it should be a fairly easy replacement because it's now held in place with nuts and bolts instead of the factor rivets.
