My drivers side window will no longer go up. The 3 other windows, when controlled from the drivers switch panel - go down when switches are in the up position. The power door locks also quit working. 12V and ground signals are good at the switch cluster. It has been acting weird like this for about 3 months.

Has anyone seen or heard of this problem. It's almost like there is a voltage polarity inversion occuring - that feeds the motors - which would explain why things are operating backwards. I guess the problem is in the switch cluster since there are a lot of active electronic components in there...?????

I'd say replace the drivers side switch panel. Your problem is probably in there somewhere. It's not really a polarity issue since the main switch only has one wire going to each of the other three windows and controls up/down by a differnt voltage level (12 for up and 4.5 for down I think)

Also, your drivers side window may have a problem with the regulator so that's why it wont go up. This is a very common problem with our maximas. 99% of the time that a window no longer goes up and starts to fall on its own, it's the regulator. For instructions on replacing the regulator, go to my site in the how to (link in sig)
good luck

 

Yeah ..I think you're right about the switch panel. The rear and passenger windows operate fine when switching locally, but not when using the driver's switch panel.

Also, I replaced the driver's side regulator a year ago. Surely that thing hasn't gone out already (although it's possible). I am thinking that the fault lies in switch panel circuitry - which is causing the window to not operate, not to mention effecting other switch functions.

I have similar problems here...

I was told that the relay switch is at fault for both the drivers window and door locks, both different relays. The door locks relay is behind the stearing column, but i think these are the problems. I think replacing the entire electronics pad in the drivers door is your best option for the windows.

But is anyone else sure?

Yeah ...I opened up the unit and found excessive corrosion on a few of the surface mount transistors and found a trace that was lifted on the circuit board. I soldered a couple of jumpers to take care of that and also cleaned the corrosion and will test tonight. The part is 130.00 at the dealership, or 50.00 at the junkyard (which is probably the route that I'll take if my repair doesn't work.

OK..hopefully this will help someone in the future. My problems were indeed in the driver's door switch panel. I replaced the switch and all is well.

The way to check these things is to measure for battery voltage on one wire of the motor and ground on the other while switching the switch. You should measure +12V or -12V. The polarity is inverted when going in the other direction. I had no voltage out the switch to the motor in either direction, hense the switch was the culprit.
