1988 9000 Turbo 2.0 l.the air conditioner pumps out hot iar. It was converted to R134a 2 years ago. I thought it was low on freon, but a guage on the low pressure side of the compressor read in the red zone. I am wondering if the Over pressure release valve might be malfunctioning.

Any thoughts or advice would be appreciated.

Ah Hah!! I took apart the pully and clutch and discovered that it was missing parts. The center shaft coming out of the compressor is splined and threaded in the middle. Nothing on the spline or screwed into the threads. Must have fallen off. Will get pictures/diagrams and replace as needed.
