Yes. I meant compressor. Also the rpms 600 to 1200. Tried to add a can in the beginning, (Which is what I thought it only needed) It didn't work. That's when I started to look at trying to figure out what was going on and why I couldn't charge it. The gauge on the can is the gauge I've been using to come up with the psi numbers.

 

ok, but the numbers have changed since you added the can. It may be you have a leak and you are now low again (from the original point seeing the PSI has also changed along with the more serious lack of cooling). If so, you need to find the leak and fix before you go on. If you don't, eventually you could deplete the oil from the system and burn out your system which will cost more in the long run. How long was the system operational before you added the can (was it fucntioning)? Are you familiar with cooling systems or is this a newer venture? I only ask because I made some assumptionns from the start that may be leading/causing more trouble than it should be.

 

When I first bought the car, it would blow hot about 90% of the time. It would blow cool (not real cold) When the psi was dropping. I tried adding a can, because I thought it was low. That's when I first saw the psi numbers and they were in the yellow area (45 to 65psi). The blue (ok) area on the gauge is 25 to 45psi. I now see on the side of the gauge that there is a sticker that says if it's in the yellow it could be overcharged. Could that be why after we did the dig mode the psi went really high? I doubt if there is a way I can let some out so I can get the psi down. Could this be my problem (overcharge) from the beginning, and the psi went higher because I originally started to add a can and it was already overcharged? And yeah, A/C is a newer venture for me.

 

When you added the can, what type of freon was it (R12 or 134a)? When you added the can, did you invert it? If not, you may have done a "vapor charge" only, and not added the other contents of the "blend" in the can. If so, the system should be completly depleted and recharged. Also, if there is/was a leak, the line oil may be low. There is no way to measure this though and the shop manual has a procedure to drain and refill, but once again you don't have the eq. (need to pull a vac on the system if the lines have been opened).

P.S. AC is a new venture for me also, I am getting most of this advice for you through a friend of mine who has been a AC tech for 15 years (the rest from the shop manual). His suggestion was basicly a start from scratch because you can't tell what is going on without the proper equipment (the high side guage and temp probe). It may be best if you just bring it to someone with the proper equipment (and cheaper in the long run).

 

Ok. Got it going. The problem was that it was WAY overcharged. We drained it compleatly and filled it with new freon. It works good. Thank you for all your help.

 

I'm glad to hear it's up and running!At least it's fixed before the really hotest part of summer started!
