AC problem

okay Iv changed the compressor, Condenser, Expansion valve, and filter dryer and still no cooling.. my high side is low and low side is high! Acts like it’s bad a compressor but I’ve tried 4 different denso compressors and blew the lines out like 100 times.. am I missing somthing?

 

Give it sometime someone will speak!

 

Lol Iv been working on this thing for a week when it should’ve only be a day...a little impatient sorry

 

Why are you blowing hoses?

Is the compressor not shutting off when it reaches cut out pressure.?

You pressure sensor that tells the relay to open doesn't sound like it's functional.

Compressors are dumb. They will keep pumping as long as the clutch is engaged. Why is the clutch not opening up.

Get these questions answered and report what you find.

Please get back to us. I love a good mistery.

 

I just blew he lines out because it acts like it’s got restriction idk I was out of ideas ... And where would the pressure sensor be? under the dash?

 

Got it. You mean you blew the system out with compressed air or nitrogen?

 

Yes, nitrogen.

 

Are you pulling a vacuum with a vacuum pump after that?

If not, you will have issues like you listed.

 

yes sir it pulls down to like 200 microns.

 

It’s a mystery for damn sure

 

@keaker

You want to weigh in on this issue?

 

I am guessing your working on the 99 ??

Let me back up just how did you get to this point AC just quit working or it never worked and you decided to try to make it work?

I have seen strange things is it possible the system sat open to the air to the point the Evap coil is just corroded and is now blocked?

Just what kind of numbers are you getting high and low are quite vague .

The more we know the better we can help

 

It worked fine and then all of a sudden it didn’t.. and my low side is like 350 and my high side is like 70.. After I put four different compressors on it I took it to a good mechanic I know he’s had it for a week and changed every single part except the lines.. that’s next but had to order them they were hard to find.
