98 with ACC no Blower for AC/Heat
 

The blower in my blazer with ACC (Automatic Climate Control) has quit working. I have replaced the module (relay) under the hood near the blower motor, the blower motor, and the ACC head unit in the dash. All fuses have been checked, and as far as I can tell, the wiring appears to check out. I have went through the "reset" procedure listed in other threads on the forum, but am at my wits end.

Every once in a while the blower will work momentarily, or cycle on and off, but this is short lived. I am hoping that someone can point me in the right direction to getting this working again. I am hoping to aviod the expensive trip to the dealer.

Any help or ideas are greatly appreciated. Thanks in advance.

Could the cabin temperature sensor be causing me problems? I am just fishing for ideas now...
