Grand Prix wont start

Possible ignition module heat failure

on certain models wires--modules--relays gain resistence from wear-then heatup--try driving no more then an hour-then coolit a few hrs--get to a electric specialist soon n lettum run a data stream to pinpoint

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

The next step is to have the engine control module scanned for fault codes.

I would have the control module tested. Some parts stores can test them. If that's ok, you might have some bad injectors.

bad fuel pump.- just replace it and your good to go!

Ignition switch faulty.

my 1998 grand prix does the exact same thing. It just shuts off while driving. I still have battery power. I have called pontiac dealers in my area and they dont seem to have any idea to fixing without changing everything in hopes the hit the problem
Can you narrow it down.

do you have any thing extra hooked up to your battery because i have a 96 and my amp kills the car when im sitting still abs light cuts on then i lose power for a few seconds

crank sensor is a common fault
