A/C compressor belt blew

[Drew96]

A/C compressor belt blew, just put a new one in and now the a/c won’t blow cold. Clutch on the compressor works just no cold air... anyone had this problem? On a 2014 Sierra 1500

Thanks

So, you popped the hood and verified that the compressor clutch is engaging and the compressor itself is spinning properly?  And did you do a quick check that the tensioner/idler for the belt spin freely before putting on the belt?

there is no tensioner, gm uses stretch belts

Belt is on correctly. Clutch works. Just no cold air.

is the clutch cycling off and on, if so then you are low on freon
