Engine Size: 3.5L
Ambient Temp: 70
Pressure Low: 56
Pressure High: 170
I work in auto parts sales and was hoping for some insight about a customerÃ¢ÂÂs a/c problem. I read this forum all the time and find it very helpful.
He replaced the compressor and desiccant bag only (He did not replace the expansion valves or flush the system.) on 1999 Honda Odyssey last May. It worked fine until last week. The compressor has stopped cooling and is making noise. The low side is 56 and the high side is 170 at 1500rpms with the front and rear blowers on high. With just the front blower on high and 1500rpms the readings are low side 53 and high side 140. The vent temp is 68. When the engine was shut off the gauges equalized within a few seconds.
Any ideas on what the problem could be?
Your response is greatly appreciated.
Check the fan(s) on the condensor, and check the air path as well.
Check for re-heating of the low side, either a blend door or hot water valve.
The compressor is pumping, but the heat is not being removed from the cabin. The compressor noise is probably related to high load - is it reman unit?

thank you for your reply.
It's reman, but we sell a lot from this company and have very few problems.
Does the compressor turn smooth and quiet by hand? Compare to another unit.
What does it do with front fan on low and rear off? If the low side doesn't come down drastically, could have one of the TXVs stuck open. Probably the front since the rear does have some response.
