91 z24 blowing fuse

I've got a 91 cavalier z24 that keeps blowing the HVAC,heater and A/C fuse.As soon as I replace one,the new one is blown.Any ideas what might cause this?Thanks.

Oh yeah, The fuse is blowing as soon as I turn the ignition to the run position, before the car starts. Everything else is working fine.

Try to disconect the blower motor and then replace the fuse. if it blew then there is a dead short. If it doesn't blow after the motor is disconected then it is the motor.:banghead:

Look for ANY crimped wires by the ecu and other places.

Thanks, I will try that and look around at the wiring.

Let us know what you find.

if your heater/ac is turned OFF when you turn on the ignition, its not your blower motor. if that is the case its definetely a short, if its ever had an aftermarket stereo in it, i'd start behind the stereo

Been looking and can't see any crimped or bald wires. How can I get the gear shift handle off? I,m trying to get a good look behind the heat/ac control panel, but the shifter handle is in the way.

auto or stick

Auto, I found the pin in the front, looks like a big staple. I'm gonna look around this evening.

yea take it out and the pull up

Well, I looked around everywhere I could see. Unplugged all the wires from the control panel and hooked them all back up one at a time to see when the fuse would go, but it never did. Put everything back together and all is working fine again, ...for now.

and now i'm back to blown fuses. any suggestions?

could one of the switches be causing this, like the blower or a/c switch, or the ignition switch?
