Ok so it's gonna be in the 90's starting Tommorow. I just found the ac relay in the console, plugged it in . the compressor comes on for 2 seconds then cuts out for about 10 seconds.it keeps cycling steady like this.the air blows cool like its trying.I checked R-134 pressure it was very high on my cheapo gauge
I dumped(environmentally correct) some now it's in the normal range. No change.the e fan does work. The compressor cycles even when it's on the heat setting.prob why PO pulled the relay
Where should I start diagnosing?any
Suggestions?

What was the pressure? And we're you on the low side or high side?
Low side has smaller valve..

muskrat

It was 130psi

I just checked pressure with engine running
Turns on at 45psi
Turn off at 20 psi
As soon as it gets to 45 the clutch engages
For 2 seconds
Thanks for any help!

Oh yeah

My interdynanics gauge only fits lo side

Sounds like needs more Freon.

X2 usual reading on a mild day in my area are 35-40 low side and 150-200 on high side.

I have a small can with 3 ozs R134

And8.5 ozs pag oil
I'll try that

No oil ....

muskrat

Now it's 64 psi

24psi
It's cycling 4seconds on 8 seconds off
Am I getting warmer? No pun intended!
Thanks
BTW it was only engaging for 2 seconds when it was way overcharged (in the red on the gauge warning !)
I'm doing this at the local bar! Ha
