A/C only blowing out of passenger side? - Toyota Yaris Forums

Actually I have a quick question for those of you who know about AC systems.

Do I have to replace the drier at the same time as the line? I'm getting conflicting answers saying it you change any part you should replace the drier at the same time to prevent any moisture in the system, but I don't know.

The general rule of thumb with A/C is that you do replace the drier when replacing parts on a leaking system, but considering that yours still had some freon in it (i.e. did not completely vent), you would be safe with not replacing it.

Well when I replace the liquid line I'm going to have to have the entire system evacuated aren't I? I don't want to have any of the 134a vent to the atmosphere.

I ordered a replacement drier desiccant bag anyways (I think it was $28).

Correct. It will have to be evacuated before replacing the part, and then again once the part is on to remove any particulate and moisture.

Alright good. Glad I ordered a replacement then.

Hoping I can get the replacement line in a couple of weeks because August is going to be hot.
