The car listed above is a gtp model.

A/C always worked then one day it stopped blowing cold air. I can see the compressor turning. I tried a bottle of subzero. When I put it on and pulled the trigger it would go straight to the red zone. I'm not sure what to do.

Good afternoon.

You need a full set of gauges to see the high and low side readings.

If the compressor is engaged, you may have a bad compressor but needs to be confirmed with the gauge readings.
