At any given time while driving or just ideling the dash light for brakes and antilock will come on and the circute for the air conditioner, power windows will shut down, and then somtimes sooner or later the circut radomley comes back on. This is bad news in the summer in florida because the air quits and the windows wont go down! HELP!

Hi, Thanks for the donation. I'd have to check circuits to and from the ignition switch. The orange wire in the diagram goes hot with the key on, carries voltage to power window circuit breaker and part of hvac system. You can use a testlite at the power window circuit breaker circuit, unplug the breaker where necessary, key on see if circuit is hot?

When breaker isn't hot, check feed to switch. If that is ok, I suspect the ignition switch. Key has to be on, to get voltage at the breaker.
