My car was in the shop for a week or so. My drivers side window worked b4 dropping it off, although it was a lil slower than new. However it never once froze up while going up or down as the classic motor failures do. So it failed suddenly without warning-luckily its up. I dont here any operation from the motor when depressing the switch. I have replaced this motor once b4 too.

I need to know what else besides the motor it could be b4 pulling it apart cause i have never heard of these failing suddenly like this-(i just searched many threads here and on ls1tech) My passenger side still works btw. Thanks.

 

You can look at the switch, but one of mine died suddenly after it only being slow for while and doing the hesitation thing a couple times.

 

How can I check the switch?

 

With a meter and a schematic. You can also try jumpering power and ground to the motor to see if it works.

 

Shoebox can you elaborate on the test? I do have a multimeter but I'm ignorant when it comes to this electrical stuff. Thanks.

 

It's impossilble to school someone on reading schematics in a thread like this. I'll try the Cliff Notes version.

terminal positions

The following is tested on the switch (disconnected from the car)

LH switch not operated:
you should have continuity from:
A to D and E (and to B and C of the RH switch)

LH switch in UP position:
you should have continuity from:
D to F
A to E

LH switch in DOWN position:
you should have continuity from:
F to E
A to D

I hope I got it right.

 

Mine's the passenger side and won't work with either door switch, drivers side is fine. Your's is most likely the motor too.

 

hate to be the bearer of bad news, but replacing driver's side window motors often is just part of owning an f-body. I've had 2 4th gens and both of them wound up making me replace them. A little trick to making them last a little longer is not letting the window go all the way down on the one touch express down...it makes the motor bind up for a couple of seconds after the window goes all the way down, ruins the motor.

 

OK i found out the motor is ok but with the motor disconected from the window gear the window switch only makes it go up. Nothing happens when I push down. Now what?

 

For the heck of it I swapped the actually gray button from the passenger side control to the drivers side and presto. Thanks for the tip in your write which i skimmed too fast shoebox. You the man with all those right ups and tech info Now I just need a new button.
