I would start by double checking your work and make sure you didn't accidentally disconnect anything or do anything that would cause a ac problem, take a look at the wires just to see if there is anything obvious, check ALL fuses.ok update...............Suncore was no real help...thier techs saying no correlation tween the ac and suspension at all. so any ideas on where to look first to figure out the ac issue? thanks in advance
If nothing is found, then check to be sure there is enough pressure in the system and proceed to hvac diagnostics from there, you can buy a .pdf gm service manual off ebay there around $20-25.00
one thing to look at as noted above, check to be sure the engine temperature is reading, with no engine temp reading, ac will not operate.
the reason I say to check ALL fuses is because maybe a fuse popped in the process of working on it or even from disconnecting/reconnecting the battery.
