2004 Chevrolet Impala Repair Question
Chevrolet Impala Window Problem
Take one issue at a time. If the engine won't shut off, check voltage to and from ignition switch. As far as over-heating, how hot in degrees F? Does the radiator fan work? As far as the power windows, I'd check voltage and ground first, then check the master switch.
Are there any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader. Some of the national brand autostores will check codes for free.
