Oriface tube plugged up?
Would pull a suction on the low side.his isn't pumping.Oriface tube plugged up?
The OP reports the suction line is not cold, ruling that out. With a stuck blend door the evaporator (and suction line) gets cold but the air to the vents is hot because it has been redirected through the heater.Maybe the blend door is stuck.
Low side too high, high side too low, both about 70 psi.You can get the gauge set from Autozone as a loan-a-tool. That would really help with diagnosis.
If the pressures are the same high and low side, the compressor is not doing anything. Don't need to look any further.Low side too high, high side too low, both about 70 psi.
That would result in too high of a pressure on the high side, and too low of pressure on the low side.Oriface tube plugged up?
That's what I was thinking, but the compressor is engaged, drag on the engine, fans come on, etc.If the pressures are the same high and low side, the compressor is not doing anything. Don't need to look any further.
Could it be the expansion valve since high side and low side pressures are the same?Cooling fans on and a higher idle does not guarantee compressor activity.
That's what I'm thinking. I'm having it looked at tomorrow. I'm hoping it's something simple like a post-rebuilt error. It worked great all last summer.Sounds like compressor isn't compressing... I would be trying to learn more about that compressor control valve
Well, apparently it isn't or the high side would be going up and the low side would be dropping. Idle increasing is probably just a normal reaction by the ECU to bump idle when a call for A/C has been made.That's what I was thinking, but the compressor is engaged, drag on the engine, fans come on, etc.
agree 100% and since the car was totally taken apart all winter including a/c could be any number of things.. none of which is easy to tell over the internet.Well, apparently it isn't or the high side would be going up and the low side would be dropping.
