Having problems with your 1994 Chevrolet K1500 ?
94 chevy 1500 6cyl. When I push AC or Defog button when driving the belt will squeal horrendously, if I do it when idling engine will stall. Could it be that the compressor seizes the pulley somehow when it's turned on?
Yes, It sounds like internal issues with your compressor. Perhaps a bearing, so it must be replaced.
