AC Low Pressure Port

[Carbineone1964]

This must be the most highly guarded secret in the world..Is the Low Pressure charging port on a 1986 on the Compressor itself? Searched for an hour and could not find the answer.. Thanks

Yes it is.

Thanks

I looked and I found two ports on top the compressor..One pointed forward at the front on top, one pointing rearward on the top..Which is it?

It worked fine for 3 years till last friday..It just starting running warmer and warmer over about a two Hour period it seems.. But now the clutch will not even come on..Maybe it has a leak, maybe it is a valve, maybe the compressor finally went..Probably end of taking it in when I can afford to pay if I cannot figure it out..

high side goes to the condenser, low side comes from the interior evap core.

more than likely, the shaft seal on the compressor failed and leaked all the refrigerant out. every single second gen tercel ive owned all have had the same failure. i have also had the crimp fail on the rubber lines as well, though its a more rare thing to see.

you cannot get the compressor anymore, and full rebuild kits do not exist. you can get orings from rock auto and the shaft seal from ebay, but being able to do a diy successful rebuild is slim.

The compressor runs on a pressure switch. If the system is not at the threshold psi the power to the compressor and the auxiliary fan on the condenser does not activate. If it changed rapidly, then something failed somewhere. If it gave out over time, run a pressure check, ADD OIL, then vacuum and charge.
