[QUOTE="Poon, post: 46581, member: 1007"] Last year my A/C had a leak in compressor, so I replaced comp, dryer, and oriface tube, charged it up and it was cool but never really got cold. After that I took it to 3 different shops and they all said "that just as cold as this big old truck will get with the temps in the 90's here". Since then I have replaced oriface tube with the severe service one, did the ball valve heater core bypass, and took the evaporator core out and cleaned it ( it did need cleaning). Blender door and fresh air door are working properly. After the recharge it was a little better but no big improvement, temps coming out at around the 60 deg range. I got tired of their answers to my luke warm air so I broke down and bought some gauges yesterday and here's what I have come up with. At idle my pressures were [B]38 low side [/B]and [B]200 on the high side[/B]. at 2000 RPM the [B]low side [/B]would drop to [B]29[/B] and the [B]high side [/B]would also drop down to just over [B]150[/B]. The only knowledge I have of A/C work is from reading on forums. I'm thinking this means bad compressor. Let me know if anyone thinks I'm wrong before I spend the money on another new one. Thanks [/QUOTE]
