The car is an '05 G6 GT with the 3.5L. It has manual climate control and for the longest time the "1" setting on the control knob wouldn't put out any heat. However, 2,3,&4 worked fine so we didn't worry about it. The other day 2&3 stopped working and we just have 4 left. From what iv read it sounds like it's the resistor that needs replaced? I have read and it seems like a cheap fix but i don't want to dump a bunch of money into an install. Does anyone have any diagrams or pics of what this part looks like and where it is located? Thanks in advance.
