I just picked up an 04 comp G. I've searched everywhere but can't find my answer. It doesn't have the dual climate control. I have nothing at all, no blower no AC, the mode doesn't change. I get the little yellow light next to the AC button but I don't think the compressor is cycling. The blower motor works it was jumpered to a toggle switch. So I was wondering if anyone thought it was the blower motor control module or if it was the HVAC control module. If i scan it what codes should I look for? Also when the PO jumpered the blower motor it set the SES light, the code is for the cooling fan relay control circuit. I was messing with it when I got home and I think all they did was put the relay in upside down... But I haven't verified that. After looking I don't think the two issues are related. I appreciate any info I can get pointing me in the right direction thanks!
