I have noticed that my heater is not heating well at all. Then I discoved it is blowing hot air out of the vents on the passenger side and cold air out of the vents on the drivers side. Any ideas? Anybody know what it might cost to get something like this fixed at a repair shop? I have a sinking feeling that this problem might be a little much for me to tackle personally
Thanx

 

prolly the diverter door
