Air conditioner seems blocked

[Silver97]

Here I go again with my crazy car, When I turn on the AC it seems like something is blocking the air, it comes out cold but very little of it, I try to switch the air towards the feet and nothing it still comes out through the vents.

Any one know the fix?

Thank you

Hi there,
I would check your vacuum source for your HVAC. This is located under your right hand side inner fender skirt. This is behind your PCM.
Take a look as I am suspecting that there is a broken vacuum line there.
This would control your modes for the HVAC, and cause the problems you have.
Allthebest, c4c5

C4C5, I am lost, is this something I can fix myself? Also what is the PCM?

:confused

Hi there,
It really depends on how mechanically inclined you are.
PCM is your engine computer. It is large and silver in color. Behind that, there is a black vacuum canister, which looks like a small roll of paper towels.
There will be a vacuum line attached to it. Trace that line, and you will probably find a break in the line.
