A/C Help After 5.3 Swap
Hi Everyone. Swapped a 5.3 from a 2002 Tahoe into our 97 2 door Tahoe. We have been driving the thing all over the place because it is so much fun to drive now.
But it's getting pretty warm out now so I really need to figure out the A/C. I made the harness by combining the 97 and 02 together to just use the computer from the 02. The compressor is a Sanden 508. I have the A/C Low Pressure Switch at the Drier and an A/C High Pressure Switch installed in the high pressure line between the condenser and compressor. I tried this wiring diagram... This wiring diagram... And this wiring diagram... I do not have an A/C High Pressure Recirculation Switch installed. Honestly I did not even know that was a thing until the other day. I guess the factory compressor has a spot for that switch. The Sanden compressor has no provisions for switches. Any help with this would be greatly appreciated. I have to go to Arizona next week. Yikes. |
