98 Jeep Grand Cherokee Question

The evaporator has nothing to do w/ the belt. With the symptoms described, it's almost a certainty that your compressor has seized, PFunk.

The a/c compressor has a clutch on it. When the a/c is turned on from the cab the clutch is engaged which transfers power from the spinning pulley to the internal parts of the compressor. The smoke comes from when the clutch is engaged. The clutch engages, but then the pulley is locked up to the compressor (seized, and not spinning), which makes the belt skid across it, creating smoke.
