Well this sucks. You already replaced the blower controller resistor next to the motor correct? That being the case either the head unit or the programmer above the accelerator is the culprit. Before you buy any more parts I suggest using your red factory service manual fault trees. Then with some codes we can see what is really going on. GC

Yea, I guess I will need the book sooner or later so I will get one on order. Thanks to all who tried to help. This really is a good group of people. Chris:dancing

Let us know if you figure it out so you can close the post and help the next member out. FSMs are a great investment to keep your car running.

Looking at section 8 of the FSM I see that the CCM is also connected to the programmer. You'll have to back-probe some of the interconnect wires to see where the fault originates. At least it's a hard fault - everything I get hit with are intermittents - but my guess is the programmer.

I have a 96 C4 parts car there in Farmington at Corvette Recycling. You can try both parts and then buy the one you need....

That sounds like my best option. PM me and I will make arrangement on getting parts!
You guys are the best:handshak:

Nice of you Ron! Not sure if the programmer will work however I think the head unit is the same. GC
