I bought the wagon a few months ago at an auction, and the front passenger window and mirror could not be operated with the controls. I took the door panel off to check, and I found the looms were unplugged. I plugged it in, but immediately it appears that the motor is engaged. Hope it's not serious...any advice will help...just don't say it's going to cost me money...

 

If the loom was unplugged it was for a reason. Sounds like you may have a bad window switch that's shorted out inside and staying "ON".

I'd check each switch to see if one feels broken and if you can't feel anything obvious then check them with a meter.
