2004 chevy trailblazer idles up and down when heater is turned on


Not just the heater, but the defroster only. Turning the AC on will do the same thing. You need to clean your throttle body with the battery disconnected to fix this problem.

My 2002 Trailblazer idles rough with the AC or defrost on when stopped. It rides fine while the car is moving. I changed my battery a couple of months ago and then the problem started. Thanks for your help


I would suggest having the Alternator checked for the proper amp output. Although it may be making enough power to keep the battery charged, it may not be making enough to power the vehicle and still be the reason the engine performs rough at low RPM's under accessory load.

I have a 2002 Chevy Trailblazer. Just replaced


If you unhooked battery it will need to relearn its idle position, should help if you clean throttle blade edge and body of carbon so proper amount of idle air can enter engine.

My 2004 Chevy Trailblazer dies when I turn on the air conditioner


just check weather all spark plugs are ok, even if one misfires then turning ac on will stop the engine. during motion the ac manages to get the power from other plugs. i hope this solves ur problm.
