same thing happen to me, just recharge your your system with R134A that contains oil to lubercate the o-rings

If this is happening with the temperature for both sides set to the same value, there is a problem with the controller or the hot/cold mixer door(s). I don't have a manual yet so I don't know if there is a controller reset procedure, but a call to a local AC shop might get the answer.

It sounds 2 me like u r loosin freon. I don't have alldata on this comp. anymore so I can't help u out as far as the drivers and pass. side temp actuators. Depending on how many miles u have, its most likely that the high side schrader valve might b the problem. I c them go bad all the time!! If u have a friend with any fittings u can get a get of 134a for dirt cheap. Walmart has is 4 about $5 for a 12 oz can. U can check the valve and its very easy and fast. Only problem is there is a special socket that u have 2 get 2 replace it. But the valve is like $10. Good luck! Anymore ? hit me up.

Is it the valve? Can you go to a tire shop and and get it replace?

Here is what it looks like. U can get it just about anywhere. A fast way 2 tell if yours is leaking and you don't have an a/c checker. Fill the system up with freon and with the car running spray a little water in the high side valve(the one with the big red cap) if u c bubbles in the water and the water sprays out u have a very good starting point as 2 where ur leak is. I hope this helps a little.

add a little gas and its been find so far but, we will see.

What do u mean add a lil gas?

We add a little freon and its working fine so far.
