Another AC nitpick!

[Big Wang Bandit]

I usually drive around with my defrosters on at like 70 to keep some heat off the engine, But I can only get the Heater/AC to blow on the high setting. Anyone know of a fix or common problem that is fixable?


Cliffs - AC/heater only blows when it is set to high. Any solutions?

Ah Ha! ^ Commonness!

So just pull the dash trim and take the HVAC control unit out? Ill give it a try. Thanks JJ

Ohhhh okay hehe. I was a bit confused. This is my first venture into HVAC stuff. Ill post findings tonight!

yes, I did this repair, it is the little resistor pack under the glove box...it's almost flush with the firewall, just above the carpet...has a connector going to it...it's kinda hard to describe where it is, so I hope that was adequate...

IIRC, it was like $35 at the stealership!

umm, not yet...I am dealing with other things right now, like replacing the wires that burned, re-tapping threads in the thermo housing, and trying to figure out wihy my ABS went out on the way home (with MIL)...

Yes, the blower resistor thing is mounted underneath the glove box. You can lift the lower plastic portion up a little bit and you'll be able to see the one screw that holds it into the ducting. It's a really simple replacement. My low speed didn't work at all, but does now. It isn't that expensive of a piece.

Anyone care to point it out. I dont wanna unscrew anything I shouldn't lol. Im accually enjoyingt he AC.

Argh - i had this thing on mine - the AC works but no blower motor for anything. The resistor pack had gone on mine and was about 24 quid iirc from the dealership. Make sure you get the right resistor pack! If in doubt, take in your old one - i didnt and made the mistake of ordering the one for the non automatic aircon - which i actually have.

Still, that didnt fix my problem and i still have no blower - which is really starting to annoy me! If i still get heat and A/C but only while driving along and the vents open to the outside world - is it going to be the control unit, the breaker on the passenger side, or the blower motor itself??

Does it run on manual at any speed? What year is the car?

Blower doesnt work at all, on any speed. It's an '88 model.
