I just bought a '92 SC300. I love it, but I have a problem. The "heater" fuse (#2 slot, 10A) kept blowing, with or without AC on. Tried 15A, they blew also. Then 30A which won't blow. I noticed a pully noise, so checked under the hood and the AC compressor clutch turns slowly, intermittently at idle. Turn on the AC and it blows cold, but goes on and off (climate control) and the light blinks. If the compressor was shot, I wouldn't get cold air. Any ideas?
