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.
