ac probs

I know this is not a dodge group but there are good peeps here so i
thought i would ask.
anyone with experience on ac systems in a 96 neon?
both cooling fans come on when ac is switched on so thats ok
but when i stop at a light my ac get quite warm on excessive hot days.
i checked the pressures
idle
55-58 psi low side
180-190 high side

i added a small amount of 134 a

idle 60-62 psi low
200-210 high side

rev it up a bit like to 2 grand and
2000 rpm
35-38 low side
250-300 high
sorry i never saw the guages while reving the car but thats what i was told.
is this right for 134 -a equipped cars?
by the way while driving like about 30 miles an hour steady the ac cools
off ok and on the highway is ice cold.

Looks like the compressor is getting weak. Your pressures look good at 2000
rpm. You can try to help it out by running it on max and making sure the
radiator and condensor are clean.

Re: ac probs

your low side pressures are way to high. the max pressure for low side
should be 45 lbs.

Right, it is high at IDLE. Normal at 2000 RPM, that means the compressor
isnt working well.
