blower switch

[jcmtbfreak]

Wasn't sure exactly where to post this. I have one speed out of four on my blower switch. The highest speed only. When I first got it, the first three worked, but the highest one didn't, then it switched randomly. We are recharging the air conditioning system when I go home this weekend for fall break (yeah, I know, just in time for winter lol. ), we would like to fix this as well while we are at it. Where do you guys think we should look first? Is it the switch itself, some relays, any guess is better than mine.

mjones would be better off telling you on that, i havent bought one or changed one on a bII. but thats whats wrong with it

1 plug to unplug and 2 small bolts to take out. Then replace and re-install bolts & plug.

Wait....one more thing. Is this a part that I can get at the parts house, or do I need to get the ford specific part? I know there is the occasional part that isn't worth getting at a parts house. What about this one?

 

[mjonesjr]

You MIGHT, and I use might as a light term, be able to get it at a place like O'Reilly.

So it's not an issue of quality, more of availability. I'll go check on it.

Where is this resistor located? I've only got high on mine and it's one of the things that I need to fix as it bugs the shit out of me.

WHAT!?!?!?! You of all people I am surprised by this.

The resistor is located on the heater box by the fan. It is the only thing on the heater box besides the fan that has wires going to it.
