is it just me or all the motors seem to be slow? Mine take forever to go down, do i need a new motor for it?

 

My windows are slower than my other cars but this weekend I replaced the motor and it's much better. The driver side window gets used alot and it started getting slower and slower. It then started stopping while moving up or down. Finally it would move only an inch or so. But instead of removing the entire regulator assembly, I removed only the motor.

After removing the trim panel and with the window fully up & wedged, I located the rivets (3) holding the motor to the regulator (feeling the back of the motor housing, I felt three bumps). Two of the rivets could be seen but unfortunately, I couldn't get to the rivets without drilling through the door. I used a 3/8 or 1/2 inch drill bit to drill through the door. I could then see the rivets. Using a 3/16 inch drill bit, I drilled out the rivets. The motor easily came out the front access hole. The replacement motor came with the slotted head bolts and nuts. I used medium strength loktite to keep the nuts from loosening. I inserted the screw driver through the drilled hole and needle nosed pliers on the back to hold the nut. It took about 1 1/2 hour but the next time will probably take 30 minutes. The local dealer quoted $300 while the lifetime motor cost less than $50 at a major chain parts store.

 

The most common reason for slow window motors is lack of lubrication. You can add medium to heavy grease to the window tracks, as well as the arms, etc. If the lube doesn't help, then most likely the window has been run dry to long, causing the motor to be on the way out. These windows are a heck of a lot slower than most windows I've had in the past anyway, but a quick lube job made mine quite a bit quicker than when I first got the car.

33now48, got a part number for the motor-only assembly? That might come in usefull...

 

I got the replacement motor from AutoZone. It is Siemens WL42000 and has a bar code number of 53674 42000.

 

How much?

 

$42.95 plus tax. It wasn't difficult at all and since I didn't remove the regulator, I didn't have to worry about the couterbalance spring and re-aligning the window.

 

i did the same thing as 33now48 did and my window has been working great now for 1 year +. i hardly used any type of lubricant other than some sort of graphite stuff my grandfather had sitting around.

u be surprised what kinda stuff u find at the bottom of a door, i found two screws and some small pebbles.

cant wait to do my drivers side window motor, its showing the same signs my passengers side did, not just there yet; i like to wait untill the window completely stops moving, makes its more fun.

 

My friend just had the same problem with his '92 RS. Like they said, motors.

 

Well, me thinks that I will have to be going that route shortly as well. *sigh*

 

is it possible to use other vehicle motors...possibly ones that are faster? granted the glass is quite large but there must be some motors out there that work better.

also, what's the hardest part of replacement? how do you re-rivet the motor back in? i don't want to have to drill holes through everything to remove my motor.

 

How about 4th gen motors?

 

in response to finding things in the bottom of the door, i found something under the carpet on my car, a big spliff LOL.

 

Kandied91z - If you want to use rivets, I believe you would have to remove the entire regulator assemb., remove the motor from the regulator and then rivet the new motor to the regulator and then rivet the regulator to the door. I didn't want to do all that. On my 91 Camaro, drilling three small holes (about 1/2") was no big deal and saved a lot of time & frustration. I was a little concerned about the bolt & nut getting loose so that's why I added a little lok-tite. Good luck.

 

Im gonna have to take my door apart sometime.... dropped a cd inside it and the window bends the cd every time its rolled down.... im sure i got lots of crazy stuff inside there.
