Driver's Side Not Cooling

You could be low on refrigerant. Have the system checked to see how much refrigerant is in there. If you are low then look at the condensor for leaks and also pay attention to the A/C lines near the firewall for leaking orings. Good luck and let me know what they find.

Does cold air blow out at least from the driver vent? Can you see the A/C compressor clutch engage? Let me know? If you are low on freon try looking at the reciver drier from the bottom. You will see green dye all over if the seals are leaking. If theye are then you can have just the seals replaced with out replacing the drier. Also look at the A/C lines going to the evaporator at the rear firewall of engine and check for oil and dirt build up. If you see that then those seals are leaking as well, If you dont see any leaks and you have rear A/C then the seals in the rear evaporator could be leaking from there.
