This is my wife's car. I need to get her AC fixed now, so she'll quit stealing my Eurovan! (I got it's AC working thanks to advice from this forum a few months ago!)
Anyway, I think she said it "suddenly" stopped cooling, but it's hard to know if it just one day quit or perhaps was starting to wear down.
At that point, I assumed the charge was just a little low, so I used one of those cans from Wal-Mart and tried putting in a little (I didn't put much in, because it clearly wasn't doing anything). That was a few months ago; I haven't done anything since.
Until today when she asked again for me to get it fixed.
The engine was still a little warm when I put the gauges on (with my IR thermometer most of the engine bay was between 100 and 115 degrees; the block was still around 145. Ambient temp is 82. Under these conditions, the high side reads 100 psi, low side 115.
With the engine running and AC turned on (and the compressor clutch does engage), the pressures evened out to about 100 on both sides with steady needles on each gauge.
I'm thinking probably the compressor needs replaced, but wanted to get you all's opinion.
Thanks!
