Lexmus

I have a 2000 RX that has started to misbehave when trying to raise the front driver side window. The window appears to lower without issue. When the engine is off but the key is turned to accessory, the window will not move up. The other three raise and lower just fine. If I start the engine it will raise when actuated, but is unreliable if I stop and then try to restart the upwards movement.. When the engine is off and the key is turned to acc, I hear a clicking sound when I engage the window switch, but no window movement.

I only had a short amount of time to work on this before my daughter was returning to college with the car. After reading a few relevant threads, I took apart the switch assembly and cleaned the switch pads on the PCB and the carbon-tipped silicone actuators, but that did not improve things. I put everything back together, was able to get the window closed and depressed the lock button for the window switches so the window wouldn't get lowered by accident while the car was away.

Later, I found and read more threads on this issue, and it sounds like often this problem can be can caused by a faulty relay on the window switch. But the engine vs battery effect makes me think it may also be a power issue. And the fact I hear a clicking sound makes me think the relay is functional to some degree. However, most people seem to resolve the issue by replacing the window switch assembly.

Given the high cost of a replacement window switch assembly (over $500 new and over $200 used), my thought is to order a replacement relay to have ready to change out once the car is back, but I haven't been able to find details of the part anywhere.

Does anyone have the info on that relay to share so I could order one?
