Truck in question is the '93 C3500 regular cab dually 7.4 / NV4500, last year for R12 systems in these trucks.
Bought it with non-working A/C, the electrical connector to the compressor clutch is broken off. Considering a new clutch is $100 and I'd still have this beat-up old 160K+ mile compressor that may not be any good after all.. and a NEW compressor kit w/dryer etc. is about $200 depending on brand, or $300 with condenser included........seems dumb for me to replace the clutch.
Moving on -
1. Just replace the compressor, dryer, orifice tube.. or do the condenser as well? Kit comes with all the o-rings for the entire system, but I'm leery of pulling apart connections that may be seized. I do know I'll be pulling several things loose anyway to flush out the system with solvent before putting the new parts on, though. Leaning towards the GPD 9611682 kit with the upgraded scroll design compressor.
2. Kit comes with "black" orifice tube. I'm in Houston where it's stupid hot and humid in the summer, I mean we're roasting down here. I've seen others mention the "red" tube. What should I get?
3. Converting to R134a seems like I have no other option but this, or to hunt pricey R12. Thoughts? Considering GPD 1311423 retrofit kit.
