ac help
I just picked up my c5 from the mechanic wednesday after i took it in because of the air coming out of all vents problem. they replaced the driver side temp door actuator & the driver side air flow diverter actuator. After picking up the car it now blows cold on passenger & not so on the driver side, it also seems not to be blowing the air volume from front center vent like it did before. i did the fuse 27 thing and I'm not sure it helped...i paid good $ to get this fixed ,and now i have this new issue...should the shop calibrate anything on the actuator or something? or is there something i can do on my end?

Do you have any codes?
A code would tell you if it was an actuator AND an actuator WOULD cause air to blow warm on one side and cool on the other...it could also be the wrong pressure in the AC system itself(R134 high/low)
If there are no codes though my bet it what lucky said

No vacuum sounds like the problem probably battery acid on the hard lines
Had the air from all vent problem. Disintegrated vacuum lines and bad check valve.

If you're getting cold air on one side and not the other, I dont' think it's the compressor. I could be wrong.
Okay, when you say 'air out of all vents'...do mean literally? I mean, was air equally coming out of the defroster 33 percent, upper vents 33 percent and lower/feet vents 33 percent? Regardless of what setting you had it on?
If you had it on HEAD ONLY. There should be ZERO air coming out of the feet vents.
Is this what you mean by air out of all vents?
Or, do you mean, cold air on one side and warm on the other?
Do you have any codes?
I don't mean visible check engine light. On the right side of your gauge cluster...press and hold number 4, simultaneously press number 1 four times while holding number 4. You will enter diagnostic mode. Grab a pen and bring it with you if it's your first time.
you're looking for ANY codes in the "HVAC" section...it'll be like the 7th or 8th 'module' that will pop up.

and on your AC re-charge, it sounds like the guy was just telling you how much R 134a he added to your system. What is also important is what were the final high/low side pressures @ a given RPM

it was the temp door actuator, which had been identified as the problem by another shop...they showed me the replaced actuator that had a metal piece broken off,i have read other post on here with that exact break on that part..the all vent issue is also well posted on...

these are 2 separate issues,the all vent issue ,blows little air and the vents wont change modes...the warm driver/cold passenger is a different issue,which cant be anything from re-indexing the actuator to high side freon charge, to worst case compressor leak...i think.....
