advice on troubleshooting?

the problem was intermittent a month or so ago, now none of the windows open. fuses/breakers to check?


there is no whining to suggest that the motors are running and the windows are stuck. hit the switch, nothing happens

help?

and now they work again.... im guessing master switch..?

Intermittent problems with power accessories is probably more due to bad grounds or damaged wires. Did you find this thread follow the recommendations? https://www.gmforum.com/t278980/

If you did, you and you still have the problem, you will need to start chasing wires down with a multi-meter and check relays.

now that sounds plausable,

bus bar clean as a whistle... anyone have a power window schematic?
