This is just a heads-up for those of you who will be replacing your window lift motors and using the Dorman unit (which replaced the Siemens unit at Autozone, PN 742-101 = PN WL42014).

The hardware that came with the unit was too short to be useful. You'll need >1 inch long bolts. Double check your box before you leave or buy them separate.

I was only able to get a few threads through the nut.

 

very useful info...

 

idk what brand I used from autozone, i think it was theyre house brand, but if you get one and it feels like it just wont fit, grind down the metal piece that sits on top of the gear. it sits taller than the fatory unit so you just have to take a little off the top. thats gay though just go to o'reillys and get the part that fits

 

Thanks.

My old motor was secured by nuts/bolts so I could have reused those, but for those who have to drill out rivets they could find themselves making another trip.

 

uh oh,i just bought a window motor from them yesterday...****

 

Maybe the one I bought was an isolated problem. Let us know.

 

i got good at putting the doorman window motors in my truck. i replaced my passenger side at least every 3 months under warranty. if i have to buy one for my camaro ill either get gm or a1-cardone.

 

I can't say with 100% accuracy the exact size, but I know there is no way the bolts that came with my motor were longer than 1". Much closer to a 1/2" tops.

Are you sure the motor was seated correctly?

 

Well, I could have used the shorter ones, but I only would have been able to thread about the thickness of the nut at best. The longer bolts in the pic were the ones from the motor I removed, not the ones I bought.

As far as being seated correctly, it sat flat on the mounting bracket, the teeth lined up along with the bolt holes, so I would think so.

 

Ok, that makes sense. The bolts are pretty much as short as they can be. You are right that there is only a thread or so extra when everything is all shored up.

It has no impact on function but looking back on it longer bolts would definitely make the job easier... but there might be some clearance issues if you get too carried away with longer bolts.

 

autozone bolts for window motor i bought from them worked fine. Bolts were at least an inch,had plenty of thread...weird stuff...

 

I didn't even use the doorman bolts.. I've had problems with those cheapo screws and nuts coming undone and snaping because the nuts come loose and the motor puts enough strain on them to break them. for mine I used some high grade metric blue cap screws, washers, and nylon locking nuts and a little lock tight for added security.

 

i just replaced my original motor with a doorman today. finding the rivets were a bitch (an inspection mirror would of been handy), drilling holes to expose the rivets were a bitch, and then aligning the gears were a bitch. the bolts on the doorman did seem to small, but i think i got all the nuts completley on. you cant have them too long or else the window will come crashing down on it.

in the end, the job really wasnt that hard. it took me about 3 hours, but if i had to do it again, it take less than 1

 

+1 there... since this is my 3rd 4th gen I've changed plenty of these motors. Last one that went out on my current car I changed on my lunch brake in the parking lot at work with a cordless dewalt drill and hand tools. lol!
