climate control switch problem - only high setting

[boss281]

My climate control fan switch only has one speed working (the high speed). None of the others work. I had a similar problem once where only the defrost mode worked but that was a vacuum line came undone. I checked the vacuum line and it appears fine. Any ideas?

Is there an online shop guide anywhere?

Supposed to be online service manuals at the top of the page here where you started this thread.

Could be a simple harness connector with moisture problem under the hood.

Well, I'll start troubleshooting this weekend. The online manuals referenced in that thread by the way are no longer available...

it's your blower motor resistor. it's located right behind your glove box next to the blower motor

Ah. I JUST replaced the blower motor--wonder if that's related. Either way thanks, I'll pick one up today if I can and put it in Saturday.

I appreciate the feedback.
