I pulled the HVAC controller out and it smelled burnt. I pulled the circuit board out and found a burnt spot. I have a spare controller that would not bring the blower to full speed which I installed and the same area burned. I have no idea on how to find what is wrong. On the board the legend shows that C67 and R126 are involved. Can any help with this or recommend a knowledgeable repair source. Does anyone out there need a parts car?
