Thanks to Shogun. Following his instructions I pull the yellow and white plug the drain went down to .03A which I understand from this forum its normal drain amp. Now do I replace the IHKA module? I forgot to mention the heater air doesn't seems to blowing out of the vents. When I put the AC on the air comes out according to fan setting I've set but not when I put the heat on. I can hear the blower going but no air out of the vents. Is this mean I need to replace heater valve too?
