To your left on that pic there is a canister with a hose going to it attached to a elbow peice. Anyways that's the canister you want to replace.

 

Is there a name for that specific canister? How much do they usually run for? Im asking because im making an autozone trip tomorrow

 

That's a vacuum check valve, if he is losing freon and pressure from the a/c hose why would he need to replace that valve? His problem would be with the loss of freon and the leak from that hose first I would think.

Second, I posted a link in the beginning of this thread which would help diagnose where the vacuum loss was and simply checking the lines to figure that out and fixing that leak would restore the vacuum allowing the actuators to function properly and direct flow out the dash vents. It's a common problem or there wouldn't be a write up on it. Could be a leak elsewhere, just have to check.

**Addition** Guess it wouldn't really matter though if you went ahead and also replaced the valve since it's cheap, but could simply be one of the hoses and not the valve.

 

That check valve cost me $5 and sorry I dint read the part where he was leaking freon. Same happened in a s10 and it was that same valve. I say try it.

 

Great advice, can someone tell me where in the dash the hoses are located?can i reach any from the knee bolster?

 

You have to go to the link I posted. The article has links in it as well with diagrams and pics.

 

Like i said before you do all that just spend the $5 to try that. I remember i posted the same info for another member here and it solved his problem.

 

Yea, it isn't a difficult fix everything is cheap so it really doesn't matter. I just wanted to clarify that it could also be another hose and didn't want him to just replace the valve and hope or assume it was fixed because we would get another question on it and have to give the same responses. ha

 

Alright i'll try it and keep you guys updated thanks for the info

 

Did switching out the valve help anything? What about the freon line?
