Having problems with your 2004 Chevrolet TrailBlazer ?
My 2004 trail blazer wont start all the time. i thought it was the fuel pump because it didnt turn on. so i changed that, it started fine but that night it wouldnt start again. i put a new relay in and im still having problems. but when it does run and the heater fan is on the idol is all out of wack. it goes from 600 rpm to 200 up to 1000, it doesnt have a steady idol. if any one knows whats going on with it that would be great because im out of answers
Sounds like power problem, if youhave test equit, check the battery and altenator if not replace the battery and start it up, the battery might be soft and ur altenator is working at full yield.
