As for this issue, no one makes compressors anymore. If the core is good, it turns internally. We can have the compressor shop rebuild the customer's core. Same as buying the reman on our website, plus the freight to send it to our compressor shop.

Hey Tim, how can i get more information about ...

Hey guys, trying to help a friend with his 92 Nissan 240sx hatch. Replaced the drier and vacuumed and charged by weight with r12, but compressor doesn’t compress. I’m having a problem sourcing any type of replacement compressor. I’ve checked rock auto as well as our ACkits.com link but to no avail ...

Hey guys, so I have the old compressor out. Oil looks healthy, no metal. But upon trying to weigh the old compressor oil (I KNOW I should have used volume instead of weight :oops: ), I was only able to get roughly .8oz out. I'm sure if I tried long enough I could get closer to 1oz out, but I was ...

Okay, answered my own question. I removed the fender liner so I could stare directly at the compressor. There's a rubber dampener between the compressor shaft and the outer portion of the clutch. That dampener has broken free from the compressor shaft. So even though the compressor clutch is ...

Oh, and the thought of a slipping clutch did cross my mind as well. As did a stuck open metering device, but I cannot see that allowing zero pressure differential.

Greetings, looking for some insight on a friends 2013 Mazda CX-9. When AC button is pushed, I can watch the compressor clutch engage, fans kick on, but absolutely no pressure change occurs on the gauges.

I have dealt with clutchless AC systems ...

BTW with the usage you describe, if there is a cabin air filter, I'll bet it is clogged with dog hair

No cabin filter on this one, I think it was just constantly recirculating dog hair Airflow from vents is plenty sufficient thankfully.

Thank you to both of you. I agree that I am on borrowed time, and that it is best to replace the compressor before failure.

Come to think of it, this truck was pretty rough when I purchased it. Dog hair everywhere, looked to also be an Arkansas farm vehicle :oops: I bet it saw all kinds of low ...

If on your first test you're reading 42 PSI on the low side (~48°F evaporator temperature, and ~63°F vent temperature), I too, doubt that the hot-water valve is to blame. Toyota valves of that vintage are pretty robust.

Your second set of low-side pressures is much better, but the vent temp of 45 ...

In those same conditions, what is the temperature of the suction line close to the low side service port, give us all the temps and pressures

I'm going to be purchasing a thermocouple soon so I can reliably take line temps. If you guys have any recommendations on one I would greatly appreciate ...
