Question about 1999 Pontiac Grand Prix
I had my 1999 Pontiac Grand Prix GTP for about two years and it always had cold air. About 2 weeks ago when I first used the A/C for the season I noticed it was coming out as just air and not really cold. So I put in a can a R134 refrigerant with my A/C on full blast and afterwards I noticed that only the passenger side vents come out ice cold but the driver side vents are the same and not as near as cold. The Grand Prix has dual sided vents that can be controlled by seperate thermostats. I made sure both the drivers and passengers sides temps were at 60 with the A/C button on. Could anyone diagnose this problem? Any Suggestions? Thank you very much.
Check the ac filter, it might be dirty and thats why it is not blowing out enought cold air. The filter is located under the wiper cover but behind the firewall on the passengers side. You access this by lifting the hood and removing the rubber type gasket that holds both together, right on top of the blower unit.
