2005 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 75000 miles
I am having an issue with my heater in my 05 Grand Prix. About 8 months ago while starting it, I had smoke coming up from the cowl and into the car on the passenger side. I parked the car till now an am trying to fix the issue. I have replaced the heater relay next to the blower motor and have also replaced the blower but still no heat. I had the switch replaced about 2 years ago. Any advise as to where to look next?
