Hi All! My ac compressor doesn't turn on. I jumped it and it ran, added a little 134, low side reads 55psi. Can't get hi side Guage fitting to attach. Been converted to 134. Where is the circuit protection? I looked at the lable in the fuse box lid, nothing looks like ac, compressor etc. Thanks, Tom AKA Spend911$. P. S. Car is 911/964/C4/1991

If memory serves me right, the ac fuse is in the engine bay on the right in the black box. Do not overtighten those screw when you put the lit back on. The metal inserts in the plastic break loose and you won't get the lit back off without cutting it open.

There are a few tests posted online - try Bergville or Specialized ECU. If it's not the fuse and you have enough refrigerant - decent chance your CCU needs work. BTDT.
