so sometime my window decides to work and sometimes it doesn't ? it'll go down but then not back up and then after a bit it'll go up !!
what could it be the motor or bad grounding ?

driver side window

any help would be great !

 

The window motor is dying.

 

oh i see have you had this problem ?

 

but when it does work its very strong ?

 

I should rephrase. It's not really the window motor. It's the thermal circuit.

Read this:

Lots of info on why it's doing what it's doing.

 

and which is the thermal circuit

 

Yeah your window motor is Dead. I had the same problem. I bought the motor for $14 on ebay and installed it myself. Its an easy fix.

 

The thermal circuit is inside the window motor housing. It's widely considered a design flaw in our cars. If you read the thread I linked it explains a way to circumvent it or you could just buy a new motor and put it in.

 

yeah it'd be better to put a new one since you have to take it out to do that mod !

 

Exactly. Plus, you can get them for around 50 bucks with a lifetime warranty from most parts stores. And Shoebox has an excellent tutorial to make installation a breeze: http://shbox.com/page/windowmotor.html

 

sweet ! thanks everyone
