Okay here's the problem. Was driving my Montana and the HVAC then power windows and the wipers all quit at the same time. Everything else works .Help

I recommend studying the power supply distribution for these 3 items if they all quit at once.

Electrical diagrams can be found at bbbind.com or under repair at autozone.com.

My first guess would be the ignition switch where different leads provide switched power
outputs that may be shared by various parts of the car. The windows run in RUN or ACC.
The wipers run in RUN or ACC (I believe I'm right on that.)Power windows run in ACC
or Run. So there may be something common to them there. Burned contact inside switch.
OR burned contact in wiring in the multi-plug that plugs into the switch.

Curious, does the HVAC blower work on HIGH speed?
