Drivers side A/C

Around a year ago my drivers side A/C went out. The passenger side works fine. I checked the freon and its at the right levels. Any ideas on how to fix the problem would be greatly appreciated. Thanks.

Mine did this and I posted a reply when I fixed it. Are you SURE you have full R134 level? Sometimes it takes awhile for the can to go in and you need to shake it/hold it up so it seems to pour in. Get a good pressure meter, don't use the crappy ones that come affixed to the fill cans with red and green zones on it. I think I filled mine up to around 45 psi while ac was running and that took care of the problem. Got cold out of all vents and did nothing else put pressure test and add refrigerant.

Im pretty sure that its all the way full. But I will go and check it again.

There are actuators under the center console that control the flow of air. Getting cold air on one side and not the other is a sign that one of the actuators has gone caput. Run the system through the cycles and see when and where you get air from vents, if you get drivers floor heat but no dash ac or something like that you have a bad actuator.

This actually seems to be a fairly common problem with the 2000+ crowd this summer, and every time that I remember, the problem was not enough refrigerant in the system.

Remember, just because you have the right amount of pressure for the system to function, does not mean you have enough refrigerant. You can guess and assume by putting a can in and watching the meter that you have the right amount, but you can't tell for sure because it only goes by pressure in the system. If you continue to have the problem, take it to a shop and have them vacuum down the system and add the correct amount of refrigerant by weight and you should be all set.


As for the actuators, if you remove the sound insulator panel under the dash on the drivers side, you can see the actuator move the doors for heat or A/C. Lay down on the floor and look up under the dash right behind the center stack. Move the temperature selector from hot to cold and back again and you should see them moving. If they move all the way in both directions, that is not your problem and it is time to look into the refrigerant levels.
