The Problem I am having a little different than others on here. Everything works as it should with the A\C except for the blower. The compressor kicks on and cycles on and off as it is suppose to. However the blower motor will never come on. I bench tested the motor and it works just fine. The little box between the blower and evaporator (not sure what it is called?) I am getting 12v at the orange, the black is grounded, but im not getting anything at the purple/white. I bought another ACC unit of off ebay thinking it was bad, but it was a no go. Anyone have any ideas? I have been looking around for a wiring diagram for a blazer with ACC, would any know where I can find one?

 

THIS THREAD has the schematic that is applicable for all 98+ C88 optioned vehicles.

 

So I have put three different heater controls in the blazer...they all work, somewhat. In the mornings the blower will work, but once it warms up outside, the blower cuts off and wont work anymore. My question is, where are the temp. sensors that control the auto climate function? I noticed there are two on top of the dash, and also there are some actually inside the vents. Could these be what are causing my problem?

 

Do you have the wiring diagram for a 94 4w?

 

Completely off topic, but try a search or two and you should find them. But don't restrict yourself to '94. Search for your specific transfer case.

 

Sorry, I was not specific, I need the wire diagram of the A/C for a 94 4x4, I have looked for it and don't to find it. I will continue looking for it. Sorry again.

 

Still off topic. You have a 1st gen which doesn't have ACC. Maybe try the 1st gen section.
