1991 ZR1 40K - blinking head unit states low freon. Bought this r12 substitute stuff from amazon - supposed to be decent - however no compressor action?? Fuse checks good - jumped at all pressure switches - nothing. Removed negative battery cable - nothing. Physically I can move clutch on compressor but its not engaging. Am I missing something? Bad compressor? Any other test I should be doing. I didn't find anything in the search and the FSM is very vague. Help!
