PT Cruiser

jiffyp20 on Thu August 06, 2009 11:11 PM User is offline

Year: 2006
Make: Chrysler
Model: PT Cruiser
Refrigerant Type: R-134a
Ambient Temp: 85
Pressure Low: 55
Pressure High: 55
Country of Origin: United States

Was told compressor replaced a year ago. Refrigerant leaked out. I recharged with UV but still could not see any leaks. Cabin air is cold.
Low pressure 55, but the high is only 55. The high side line is also cold and condensating. Will take to pro, but would like some insight.

Thanks

Sounds to me like the recently-added refrigerant will leak out soon. Let the AC pro find the leak, then decide whether you or AC pro will fix the leak, evacuate, and refill. So for sure you'd need a vacuum pump, real AC gauges, and a way to find the leak.

I have a vac pump and gauges. I'm not a pro, I just don't like to be had. I'd much rather let a pro deal with this one. Just has me puzzled being new to this and all.

Thanks

Those cars are built funky. There are 2 ports on the passenger side near the firewall. A high side and a low side.....Fittings anyway.

Both are after the orifice tube so both read low side pressures only.

The actual high side port is on manifold at the compressor but I sure can't get my arm down there to connect to it.

So if your using the high side port thats easily seen your getting low side readings on your high side guage.

My mom has one. When her battery died, I had to drive home and search on the Internet how to get the battery out (she had the manual, and I used to work as a mechanic). Some air flow accessory needed to be removed first.

I think that both ports on same side was only for a year or two-- was a manufacturing snafu that finally got fixed-- I thought is was like 03-04 or so....I remember it well though...........

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
