If you have dual climate control, you most likely have a low freon level. The evaporator can get cold enough for the passenger side (where the evaporator is located), but not cold enough to transfer cold air to the passenger side. Have it inspected for a leak and the freon level topped off.

Sounds like one of the vent tubes or hoses fell off or broke on the drivers side. If air blows out but not as strong. If pressure seems the same something may be blocking the vent or only letting partial flow from ac. Check all duct work first that is usually what happens.

Are blows warm on drivers side


If the air temp is not as it should be on one side, the problem could be the controller or a blend door under the dash.

Air conditioner stopped blowing cool air. Added freon. Worked well for a few days. Now only blows cool air on passenger side.


Chances are you have a pretty fast freon leak, and the passenger side will be blowing warm within a few days. I have the same thing happen on a couple of my GM cars, except my leak is very slow; warm driver's side, cold passenger side.

You can try and top off the freon again, but I suspect you're going to have to take it to a shop to find the leak and get it fixed. Plan on spending some big dollars for the repair.

Good Luck.
