Intermittent rear windows operation

[Blueboy]

1994 RRC LWB with child lock. Yesterday the rear windows would not operate although the day before they did. Fiddled with the child lock switch and then they worked. Took the switch off and cleaned the contacts. The windows didn’t work immediately yet after the second attempt did.

Question is should I replace the child lock switch? Or is it something else I need to check?

Thx in advance for your help.

If you have a bum window switch, you can change it out with one of your known good switches. If the problem follows the switch you have found your cause. ECU solder joints can also cause this, and be intermittent. See following links (dweb).

i had the same problem, bad window switch, I moved switches around until i could isolate the dud. I keep a "good" spare in the console.

Jim's (dead) link was on the old dweb server, but it's the second link in post #2 above.

1994 has a different rear window ecu than the 95/D1. They dont fail nearly as often as the D1 style, but they still do on occasion. They can be bypassed in a similar manner. Its located under the cubby in the center console.
