The compressor clutch on my 2001 Safari won't engage, so no A/C. It works when jumpered at the relay. All the A/C parameters are OK: low and high pressure switches are closed, voltage to PMC drops to ground when A/C is switched on. All fuses are OK. According to the wiring diagram, terminal D6, supplying voltage to relay, is supposed to have voltage when the engine is running. Mine has no voltage at any time. Turn signals and backup lights are fed from the same pink wire coming from the ignition switch and they work fine.
Has anyone encountered this problem? Any help would be appreciated.
