ZR-1 Net Registry Forums - View Single Post - Cause of Blowing A/C Clutch Fuse Corrected

QB93Z · 10-31-2010

My 1993 ZR-1 had an A/C problem. The A/C Clutch 10 amp fuse was blown and since it provides power to the A/C Control module, all control and indications are lost.

My plan was to replace the A/C compressor and clutch.

However, after pulling the plenum, I discovered that the problem was a pinched wire to the compressor clutch:

Apparently the wire had been pinched between the plenum and injector housing. After the insulation wore through, the wire was shorting to ground, blowing the fuse.

Easy to fix by removing the lead from the connector and sliding a short piece of shrink tubing over the wire.

Everything OK now.
