the DPO of this otherwise excellent vehicle must have had problems with the socket and/or switch controlling the blower motor... when we first bought it, the blower would come on "HIGH" if the A/C or heat was turned on. I replaced the switch, but discovered that the actual pigtail was destroyed and the wires had been capped with quick connects, and *probably* hooked up to run default "HIGH" as they were arranged.... which is how I connected them to the new, operable switch. Which worked for a while, but wasn't used during a mild late winter and early spring... cue LATE spring and some real heat, and now the blower motor doesn't work.... I'm heading back to the pic-n-pull to get the socket and as much wiring as possible to *properly* connect the switch, but in the meantime, what else can I look for to remedy an inop fan control switch?

 

It's conceivable that the heater resistor (my 97 has one) is blown. If so it'll only run on high. The resistor is used to make a single speed motor multi speed.

The '96 has a blower resistor block as well.


See the pic below for the wire connections at the blower speed switch.

Photo dutifully stolen......

 

Which one(s)?

 

First one. Should I steal more?

 

I already have this one.

 

Nope. That should do it. That's a good pic you have of the resistor block. Pinched for my files ;-).

 

Thank you ALL!

 

For helping you, or stealing each other's photos?


LOL.

 

He probably pinched them as well.

 

Yup. Probably so.....

 

Nah, but they're here NOW.... LOL

 

Pinching each others tech photos and sharing them as needed is strongly encouraged.
