Air conditioning started slowly blowing warmer about a month ago. Could still hear compressor on/off and engine surge at idle etc etc... used ac again frequently last week and only warm air came out. looked underneath compressor doesnt turn but is free to move when by hand. engine DOES however surge a little at idle.
I went ahead and bought the el cheapo R-134a recharge kit (gauge/valve etc.) and took a stab at it. When I hooked the gauge up to what i still think is low-side charge point (5 or so inch forward of accumulator) it read about 140psi (motor was running for 10 min with ac on full blast)? Instructions said to NOT service anything higher than 45psi so i backed off and came here. Ideas?? Bad (el-cheapo) gauge??
ps compressor clutch fuse GOOD
acc belt GOOD
