Alright so,

I don't have air in my car, at all. I just tried to re-charge it. Even though it says it's at full pressure, still getting nothing. Not to mention, my front vents on the dash it's self wont work. Only the one right under the front windshield defroster. Now, what I did notice though when I started it. The A/C clutch spins for like a good 2 seconds, if that, then stops for a good 10. Just basically kicking on and off. Would this mean I need a new A/C clutch? Or something else?

Thanks for the help!

P.S. It is not fun to drive in 90 degree weather without air, just saying.

 

Well for the air blowing out of the defrost vents and not out the normal vents then your vacuum hose is most likely broke off the vacuum tree. Open the hood and look for some small rubber and plastic lines going into the vacuum tree right above the power steering pump on the drivers side. The rubber lines break after a few years. Easy and cheap to fix. As for the AC turning on and off I dont know so maybe someone else will be able to help you out.

I actually just got back from outside and realized that the damn connector for the vacuum line fell off. And the one end was actually melted shut. I just got that reconnected. But still blowing nothing but hot air into the car. And the A/C clutch is still doing the same thing. So yeah, any fixes for that would be much appreciated.

 

Sounds as if your A/C compressor may be shot. I had an A/C compressor fail (on a different vehicle) and it was doing the same as yours.. turning on and off at the clutch.

Having too much or too little freon (or whatever they call it these days) will also cause on/off, as I believe they have a "do not self destruct" mechanism built in.

You probably took the measurements on the low side, and to find out if the compressor is bad, I believe you need to check the high side.

Mine busted when temperatures were above 110* daily

 

ac works but it come out of the defroster and floor. heat or ac wont come out of the vents

 

Didn't actually read the thread did'ja there perene?

 

Just to clarify, low r134 or high r134 will cause the compressor to shut itself down. Unless you've added R134, the PSI is unlikely to be too high, but rather low, which can occur with a slow leak.

If you do find it low, they do have R134 which includes colorant to spot leaks in the system. I would suggest using it to see if there's a leak in your tube/connections, etc.

Check the PSI on the low and high ends to see if they're withing spec. Don't just arbitrarily add R134.

From the service manual, it indicates that if there's black soot inside the compressor, it suffered a catastrophic failure and needs to be replaced.

Just my $.02. Good luck.

 

And mechanics charge a fortune for a new one.

 

Easy and cheap solution - A/C DELETE for the win!!!
