Electric lift goes down but not up. Same behavior when operated by the driver and passenger switch. Pulled the relay, whacked it a bit. No change. Driver window is fine.
Suggestions on where to start? Of course I was planning to drive the car on a roadtrip tomorrow and this discombobulates the plan...
I just went through something similar, but opposite... mine wouldn't go down, but would go up. My issue turned out to be a broken wire in the driver's door.
The power for BOTH windows goes into the driver's door first - then the power for the passenger window goes OUT the drivers door, along the firewall, and into the passenger door.
It sends TWO (+) wires over to the passenger door - a separate line for UP and DOWN. Sounds like you lost your signal on the (+) wire that makes the window go up. With the key on and no buttons pressed you should have 12v at both pins 4 and 5 on the passenger switch. The switch connects ground and reverses the polarity to the motor. My guess is that you lost 12v on one of them.
From there I'd start tracing wires, from the passenger door switch, through the connector in each footwell, over to the driver's door, and figure out where you lose continuity.
You'll want to make sure that you have continuity from either pin 5 on the passenger switch (on the passenger side), all the way to pin 2 on the passenger switch on the driver's side - OR - pin 4 on the passenger switch (on the passenger side) to pin 1 on the passenger switch (on the driver's side).
Thanks. After some futzing with the lift relay, I can get the window to go up intermittently. I pulled the cover off the relay, it gets really hot - is this normal? (has a big heat sink so maybe yes?) Same level of heat on both windows, not just one side.
Right now, I'm leaning towards a fluky relay but also looking closely at Jim's advise above on the wiring.
He tested with the other switch from the driver's door.
Sorry - what I meant above is that the problem is the same regardless if you use the driver door switch or the passenger door switch to operate the window.

Ah.
Then I would first advise swapping switches around. Use the drivers window switch in both passenger window switch spots and see if the problem goes away.
If it does it's probably a bad switch as suggested above.

But if the problem is the same with the passenger door switch and the drivers door switch, my thinking is that the problem is not specific to a switch. If just one switch acted funny, then yes I would think it's a switch. But maybe I am missing the point.
I would pull the door card and see if the regulator is indeed broken. They are known to do this and in fact my car had this same problem. The regulator binds up and won't lift the window. Someone?? Maybe Rennline makes this kit to replace the roller. The OE one is not replaceable.

Passenger window goes down but not up...
