Chevrolet Traliblazer computer issues

Asked by Aug 02, 2011 at 10:24 AM about the 2002 Chevrolet TrailBlazer LT

Question type: Maintenance & Repair

Ive been having some major computer problems with my trailblazer.

Here are the symptoms : The ac shuts off when im driving, the radio display it says "needs amp". My radio will stop n start again. I cannot get my keys out of the ignition. and I cannot get it out of park. and lastly, the only way I can cut the power is by
unhooking the battery cable so it kills the power.

the engine is fine, its starts up fine.

ive checked the fuses, all of them seem to be in tact.

any ideas would greatly appreciated...

Don't know if you've found your problem yet or not, sounds like it may be a loose wire/intermittent connection. Have you tried to disconnect the battery and leave it disconnect for at least 30 min? This will reset the PCM (computer) to factory defaults.
