jmcnamer Posted June 4, 2021 Share Posted June 4, 2021 (edited) My AC motor seized up in my coach. I called Cummins and they could not tell me what compressor motor I had on my engine. Would anyone know what replacement motor I need and the best place to get it? The Cummins dealer said it "might" be a Sanden. Any help is much appreciated.

jmcnamer Posted June 4, 2021 Author Share Posted June 4, 2021 I'll see if mine has one. Do you remember where the tag was located on the pump? I looked yesterday but could not find one. Thanks again, Jody Link to comment Share on other sites More sharing options...
waterskier_1 Posted June 4, 2021 Share Posted June 4, 2021 I ordered mine from AutoAirOnline.com. I got the Seltec TM-15HS Compressor. This was for my 1997 C8.3 Dynasty. Here is the link to the page. Same price I paid back in 2017 (except I had it overnighted at $100). Link to comment Share on other sites More sharing options...

jmcnamer Posted June 14, 2021 Author Share Posted June 14, 2021 Thanks for the help with the A/C compressor. I evacuated all of the refrigerant from the system. Changed the compressor, created a vacuum to refill the refrigerant, and it took 3 1/2 cans, around 30 oz of refrigerant. Now the 12 oz cans are refilling the system, extraordinarily slow. (30 min for 6 oz) I checked the high and low pressure and its holding pressure fine. How much refrigerant will the system take, and how would you recommend charging it? Thanks again for your help.
