Default A/c help!

Background: I havent had any A/C in over a year due to the fact my car has been down for the new motor build. I finally bought the right size belt to fit the smaller UD pulley and put in a can of freon. Nothing happened. Wondering if I need to put another can in or if maybe my compressor is messed up??? Also, when i have the A/C set to Max, its blowing out at my feet, not through the top vents. Vacuum hose somewhere? And if so, which one? THANKS!

The "can of freon" is a bad thing. You need the correct charge. Hopefully the can did not have sealer in it. That stuff will trash the whole a/c system.

You need to bite the bullet and take it to a repair shop so they can pull a vacuum on the system to boil out any moisture that may have gotten in since it was apart. Then properly charge it. A can will not have the proper charge.

If you do take it to a shop, be sure to tell them you put a can of stuff in, bring the can to them so they can see if it had sealer in it. Some shops, mine included will not touch a system if it has had sealer in it.

As for the blowing on your feet, it may be a vac problem, but usually the system will default to defrost in the event that you have a vac loss. You may have other mode door issues.

you most likely left the vacuum source at back of intake off.

reach back there on pass side and find the hose and
put it back onto the fitting at back of intake.

and then go to a shop like rpmauto said.

as far as which shop you can go any chain place.
or the dealer.

A/C recharge is standard $100 job usually.

it has to have something to supply vacuum
to the brake booster and other items.

if not then your just gonna have to run
a vacuum T in the supply to booster.

im guessing it will be a 5/8 with a 1/8 nipple
off it.
