Air Conditioning problem
1992 Lexus LS 400 V8 Two Wheel Drive Automatic 120000 miles
Checked continuity on clutch solenoid: ok at 10 ohms. No voltage to clutch when activating AC. All fuses and circuit breakers checked ok. I suspect the AC control unit is the problem but since I don't have a schmatic of the AC system or a service manual I am not sure if there could be other elements or sensor failures that are causing the problem. Does anyone have an idea?
