I checked my r134a pressure and it was about 50 psi on the low side. Should it be around 40 psi at the most? Has anyone checked their a/c pressures this summer? I think it is overcharged because sometimes it cuts off - possibly because of high pressure..
A little levity is excellent for the start of summer.

well how did you re-charge it? hopefully not with one of those hokey POS "kits" from Wal-Mart, you need a high and low pressure gauge, it should be purged and re-charged correctly to work properly, I did the same thing you did and it shut off because its out of balance.
Well its true it is a cheap recharge. I don't want to spend any $ because you never know when the government will seize your car so it doesn't make sense to pay extra for correct repairs. I only have access to a low pressure reading. I think it is overcharged so I let some off. It seems to work when temperatures are lower than 90 degrees but shuts off on temperatures above 105 or so I believe the pressure is still high. It does have a slight leak so I was figuring just let it sit until it naturally lowers pressure to 40 psi on the low end. I called a dealership and one of the techs told me never to let the low pressure get above 45 psi.
