New A/C Compressor, Orifice Tube, and Accumulator, and now clutch wont engage.

Posted

Finally got around to redoing my A/C after sweating my butt off for a month. Replaced the Accumulator, Orface tube, and bought a clutched that worked from a buddy of mine, added refrigerant to it and the clutch isnt engaging when I turn on Max A/C and everything. My gauge is reading about 120 and according to my phone its about 82* right now. Anything helps, thanks!!

 

Edit: I forgot to mention the 120psi is on the low side and yes I did evacuate the system for 45min.

    Another test is to unplug the low-pressure sensor on the accumulator and use a paper clip and bridge the contacts. Typically that starts the compressor. It could be a bad high-pressure switch by the c

    Let's start with the A/C relay. Pull it out and jump across the 87 and 30 pins. Double check the Fuse J (10 Amp fuse) in the PDC. If it starts we know that circuit is working.

    Something I caught him on was the used compressor he bought had spilled out all it oil. So I'm glad it didn't fire up because it would of been a for sure black death. Then I was working at the clutch

I've used Murry A/C compressors from O'Reillys in a pinch. The last one I installed was for an 01 Chevy Taho with rear A/C, June 1, 2017.  I paid $189 for it with a limited lifetime warranty.

Here is a new Murry compressor from O'Reillys for $234.  Now, that price is in Escondido, CA  and I can't see why there is a $96 price difference between states.

The other brands I've used have been Valeo , Sanden and York.  These were for different Volvo models.

    I would just buy a NAPA thermostat and save a bunch of money at $29.

    I'm using one from Rock Auto at $14 I think, Gates 190f with good results. :shifty:

    Here is the boiling point of water at different levels of vacuum. On of the few reason I like to do A/C work at noon at the hottest part of the day and have the customer drive to me. This produces a lot of engine bay heat and all the plumbing is nice and hot. Little vacuum will go a very long ways.

    Finally got to look at my ac clutch this weekend. It seems it has worn enough that the metal plates on the front have actually rubbed the pulley enough to wear the metal thru around the outside. I just bit the bullet and ordered all new.
