Where can I find electrical schema for the radio of a 2002 pontiac Montana, I want to replace the radio by a Kenwood and I don't know which wires are for the speakers? Thanks for your help. Yves

Depends on the type of OEM radio you had in the system before the replacement. Your car may have an auxiliary amplifier between the radio and the speakers, and if so, you may have to bypass it. In any case, have a look at the original wiring diagram (Alldatadiy.com will probably help) and check your wiring again.

Which lights? the night lights or the symbol lights. if the symbol lights are the lights that are on, you need to tell me which ones. you said all lights but if it is the symbol lights then you are telling me the battery light ,oil light ,temp light, abs light, low coolant,washer fluid,check engine,brake and so on,
let me know what is on.

You would need to figure out if the thermostat is stuck closed, or not.
Most mechanics would either replace it or take it out and run the engine without it as a test. If the engine still overheats with the thermostat out, it could be a faulty water pump, restriction in the radiator, or other problems.
A blown head gasket should leak coolant out on the ground or into the engine.

Sounds like an electrical issue likely in the harness that runs from the body to the gas tank or close to the ECM and the wiring may be rubbing against the body close to the ECM and shorting out. Look for lumps in the wires or green corroded connectors.

Have you checked for a blown fuse?This is what it sounds like has happened.
