A/C help

[Blackbird WS6]

the ac turns on BUT no air comes out of the vents.....i think its vacuum leak.....does anyone know where to look or what line it is? just make it EZer for me, this is the first time this has happen

[cammed goat]

You're going to have to check both the hi and low pressure hoses for leaks. Chaser dye works well to find leaks. Are the lines new? Were they recently replaced? Or are they original?

there were replaced, dont know when tho.....the compressor turns on and all that and cold air comes out of the small vents on the pillars BUT not the 5 main vents on the dash (3 in the middle and one on each side)

[cammed goat]

No cold air? Or NO air coming from the 5 main vents?

Sounds like the blend function in the A/C controls is either disconnected, the vacuum tube is disconnected or broken causing the flap to stay shut.

so i have to take the controls out of the dash and look? or is this located some where else.....i fucking hate ac shit

You might be able to look around under the dash for loose wiring/tubing. Or pull the radio and look through the hole where the radio sits.

ok....its not anything in the engine bay right? no lines there?

[cammed goat]

I don't think so. Usually the blower is under the hood if I recall. The A/C wiring/tubing is usually under the dash. When you switch the controls to, say, defrost and then to floor, do you hear a "thud" noise?

not 100% sure...have to check later......if i dont then what?

[cammed goat]

If you don't hear that "thud" noise, then most likely the flap is stuck or there is something disconnected.

ok i didnt here the flap shut.....it blows out everywhere else BUT the (5) main vents...i started to move around some of all that crap under there and they slowly started to blow and then without a min or 2 there at full speed THEN i shout everything off and turned it back on they didnt work anymore...then out of nowhere slowly they started to blow again THEN i shout everything off again and they did the same shit....i dont know if something is lose OR WTF the problem is now

Sounds like the flap may be gummed up or jammed.

so im going to have to take all that shit apart under the dash infront of the glove box? thats going to be fun


god damnit i hate ac shit lol....its always a loose loose when working with ac crap....this is not the end of it i know lol

[cammed goat]

I suppose. But you should try to work the flap by switching the settings back and forth to see if that will set the flap back to normal.

id look at the back of your intake manifold ...on the side opposite of your brake booster line there is a small plasticy hose ..it is for your hvac system..make sure it is plugged in ..and if it is i would take off your intake and make sure it isnt broken in anyway

well it was working fine the last time i used the ac a month ago and the car only had been driven a mile if that from that time BUT ill check into it

Check the vaccume block located near the BCM up under the passenger dash kick panel near the glove box bucket.. it's round with multi colored hoses comming out of it.. Check connections and for dryrot. There could also be an obstruction in the "flapper" box..
