Well as stated i got my new engine replaced a while back. Prior to the engine swap I had frosty AC, now I dont. What can I check. It might have been something I did. Only things Ive done so far since getting the car back is Remove and reinstall upper intake manifold, install AEM intake, and new coils and spark plug wires.

Is the A/C clutch working ?

if it is, you probably have low R134a.

if it doesnt, either A/C compressor is bad or you have a leak somwhere.

They likely didn`t recharge the refrigerant after someone undid one of the lines when they swapped the engine

Or the electrical connector on the AC clutch didn`t get hooked back up

Hey there? What's up with your A/C? Hmmm.. Have you checked for some leaks somewhere already?
