Need help diagnosing power window system
'93 LS with the usual faulty window operation as others have stated in the last 6 months. Yamae mentioned in one of the posts about the mpx body computer as possibly being a culprit. I have an oem manual for the '94 but can't find any reference to this computer. The power window control system description,troubleshooting and wiring diagram only refers to the theft deterent and door lock control ecu as a possilbe cause in addition to the usual master and individual window switches, motor, fuse, relay etc..
Yamae also mentioned that the 3 passenger power window controls are controlled by the mpx body computer. Again, troubleshooting list likely causes in order of probability with no reference to a mpx body computer. I'm assuming my '93 and '94 window operations are the same.
Any and all help is much appreciated.
