You did switch out the blower resistor pack right?

I finally decided to change the resistor. The old one was all corroded. The blower still doesn't work. I checked the fuse it was blown. I put a new one in and it blew as soon as I turned on the fan. What's next... need my AC!

Anybody have a clue? If it's up to me to figure out I won't have A/C for another year.

Any help is appreciated..

I can't help but is anyone ever has a mod day just for AC repair count me in. I might even use a wrench or two. Smile

None of my cars seems to ever work. Right now the Camaro sort of works but the compressor sounds like it's going to explode and a charge only a few weeks.

If turning on the fan pops the fuse then there's a cross on the fan wire. You'll need to check the wiring to find the cross and eliminae it. It may be as simple as unplugging the resistor and the blower motor and making sure there's no corrosion in the plug itself. Also when you replaced the blower are you sure you got one with the correct amp load?

On a side thought, is the fuse the right size? I've seen plenty of cars with a fuse rated smaller or larger than what was suppossed to be in there.

The fuse is correct. I put in the blower motor from my wagon and it worked last time I used it in that car. I don't even think my blower motor was bad there is another problem. The resistor was extremely corroded.

This is tough via posting
Mode switch in OFF
Blower switch LO
Fuse doesnt blow? Correct?
Pull plug from resistor pack. Confirm fuse is OK
Switch Blower switch to HI. Confirm fuse is OK. Leave switch in HI
Unplug AC pressure switch plug from accumulator
Mode switch to MAX position
If fuse blows its the blower relay or a BAD blower (which you think is OK)
If fuse doesnt blow its the resistor pack Accumulator switch or wiring
If you use a meter you could check pin to pin on the resistor pack & make sure you have resistance between all 4 pins
Important part is you dont have any dead shorts (zero resistance in this case)
In my head this method works (thats the disclaimer... Razz )
Good luck
Edited 5 efin times to try to get it right. Report back for more help Rolling Eyes

After looking over the wire diagram and reading Ron's post I suspect it may be the blower relay.

Thanks guys for your assistance, I will go through the checklist and see what's going on.

Holy old thread but.............. I finally fixed this.. what.. 4 years later? It was a shorted wire under the hood. Relay center wire harness.
