Yes, I reset the codes and I have not seen them return. I also haven't spotted a leak anywhere.
Yeah, I have been looking in my garage for my AC gauges but haven't used them in so long and cannot remember if I loaned them out or something... my Z28 doesn't have air and I am used to it that way.. so I suppose I will have to buy a new set of gauges to really continue diagnosis. Going to lift it up and look for leaks again and verify the AC High Pressure sensor is working correctly with the AllData manual I just downloaded.
Any idea if the compressor control valve can stop the AC from working, even if the clutch is turning? Seems like this would cause damage to the compressor since it would be running dry/choked off.
/edit - Oh and if you PM me I will tell you what the price was during the promotion. I can put you in touch with my vendor if you wish.
If you find your gauges or buy some gauges. A full charged system will sit at around 110 on both hi and low when it's sitting.
What's your high pressure reading on your ethos with the car having been off for a couple of hours????????
When it's running. Fully charged will clock in around 250 on hi and you should have 30 - 35 on low. If everything is working properly.
If you're that low though, I'd go ahead and have it sucked out with a machine. Then vacuum it and fully charge it.
If you have access to a scale to measure the amount and label on your car still to tell you how much. That way you know how much to put in. YOu should end up around the 250 mark. They always end up around that mark. No matter what car or brand.
FIRST. If you have a leak detector or can come up with one. Check the evaporator. Turn fan on high and sniff the vents. WITH CAR ENGINE OFF.
