02 buick lesabre power windows Sign In

I have a 2002 buick lesabre with a 3.8 and have a passenger window that goes down useing the new drivers switch but not up, unless I removed the panel and hot wire it, so the motor works, the pass switch is missing. From what I know these are solid state and I'm wondering how to trouble shoot this system, (switch, module, motor). Is a standard 12 V tester any good for this or is it something completely different? thanks

No, I'm afraid not. This system used an electronic module to control the windows. You need a professional scan tool capable of accessing this module.

O.K. thanks for everything, With a new switch and a good motor I'll have to assume it's the module, plus I may have toasted it jumping wires trying to get it up, assuming it was common relays,I am out dated.

Can the switches be tested with a standard multimeter? It seemed to work on the rear window switch and the drivers has solid state elec. can the front pass. be tested do you know or is there a chance it can be toasted with the 9V multimeter? Thanks

If you're testing 12v with a 9v meter, you're probably going to fry it.

Watching in dismay. Do you have a passenger window stuck down till this is resolved? Take one stuck down and unplug that motor if you need time with a window up of course. It should still be just two wires to a motor (don't involve the car or the switching at all) and if you power it sometimes with even a 9V household battery or two in series you can nudge it up. Swap polarity if you pick the wrong way. Don't do a thing unless you know it is just to the motor itself.


If you have a jumper box you could use that - just to put the dang window up. AGAIN - this only with motor isolated from the whole car like it's on the floor or work bench type thing,

You're not going to move that window with a dozen 9v batteries. Too much current draw for that. I think he's already powered it directly anyway.

Sure can sport, if still pushing a window you just help it and it will go. Bad motors will not. Do it all the time hunting down used parts and dinky motors to who knows what. They don't let people drive out in the yards and would like to know if things work or not in assorted wrecks or junks and I'm not carrying a heavy battery for pick your own places, T


(Just back as I keep spares. ONE 9v turned a late 60's ^ thru 80s PW motor which are about like a starter on some cars now - it turned)

Re: 02 buick lesabre power windows Sign In

I got the window up,The car went to a body shop and they determined the drivers switch was bad but the drivers motor was good, , they had to get windows down to do the paint job and spent a little time checking them out.I bought the new drivers switch and only the rear windows work, and the pass. front goes down but not up. I had to replace the rear drvrs window regulator and used a tester sending the 9V battery through the switch testing for continuity to see how it operates. There were 2 wires and a blk/wht, the switch would ground one or the other for up & down, I don't know what electronics are in that switch but it still works. I know the drivers switch is solid state so I don't even want to send any current through that one, I don't know about the front pass. but I tried to put it up the first time by jumping wires through the module on the switch disconect, it didn't work, and at first the yellow wire was hot and now it's not so I beleive that module is a goner. I went to the dealership and the drivers module is about $500. So now I have to go to the scrap yard but I'm looking for an entire car for parts at these prices. If I didn't care I would remove the motor and put a hand crank on it but my wife is not about to go for that. Thanks again

dr.donut! I'm NOT suggesting using a 9v battery for testing anything that could involve the vehicle's devices RATHER it can make assorted motors either work or enable a power window to go up with a push at the same time - ALL OR ANY OF THAT NOT INVOLVING THE CAR AND JUST THE ITEM UNPLUGGED AS IF IT WAS OFF THE CAR!


Know, not guess when something like that could help. Not for general use but you said a window went down and not back up and know how annoying that could be if you needed more time and use of the car to do whatever to properly fix and still use the car, that's all.........

Re: 02 buick lesabre power windows Sign In

I went to the salvage yard and got a switch and module for the front pass. and it went down but not up,same as before. I checked the drivers window motor and contrary to what the body shop said it didn't work, so after replacing it the drivers window works. But still the front pass. only goes down, so I hot wired it up and put it all back together, could it be two modules with the same fault? I'll call the salvage yard and see what they have to say.$65** for the module and switch, not bad.
