2004 Buick rendezvous will not start

Check your connections to your battery and your fuses and relays.

Thank you for the response brotherben. I changed every fuse and relay and the battery is connected because the lights work. The power door locks work. The dome lights work. The turn signals and emergency blinkers work. The power seats work. The things that don't work are the radio, the instrument gauges, power windows, air conditioner.

Thank you for your response Ed92626. I will check that and let you know if that is the problem.

Thanks Ed92626 but no luck. I changed the ignition switch and same thing, no start

Did you ever figure this out???

I would have checked the connections at the started. A lot of GM vehicles use a fuseable link at the starter/solenoid connections. Simple test light test will find the problem. Good luck!
