RECENTLY BOTH COOLING FANS ON THE CAR HAVE STOPPED RUNNING. THE CAR HAS BEEN OVERHEATING IN TRAFFIC. ALSO, WHEN THE AC IS TURNED ON THE COOLING FANS DO NOT RUN AS THEY HAVE IN THE PAST. THE QUICK AND EASY FIX, AND ONE I HAVE DONE IN THE PAST, WAS REPLACE THE COOLING FAN THERMAL SWITCH IN THE RADIATOR. THAT DID NO GOOD. USING THE BENTLEY MANUAL FOR THE CAR I DISCOVERED THAT IT IS MISSING MANY OF THE CIRCUITS RELATED TO THE AC SYSTEM, AND THE LAYOUTS OF THE RELAY AND FUSE PANELS HAVE ERRORS. I HAVE SINCE FOUND MORE ACCURATE DIAGRAMS AT ALLDATA. I HAVE LOCATED AND CHECKED THE FUSE, THE 2 FAN CONTROL RELAYS, B+ TO THE RELAYS, POWER TO BOTH CIRCUITS INTO THE FAN CONTROL THERMAL SWITCH, AND THE GROUNDS. I HAVE SYSTEMATICALLY JUMPERED AROUND EACH COMPONENT EXCEPT AS NOTED BELOW AND EVERYTHING SEEMS OK. THERE IS A POWER RESISTOR TO REDUCE THE FAN SPEED THAT I CANNOT FIND, AND I CANNOT CHECK THE FANS, AS THE POSITIVE LEAD TO BOTH OF THEM DISAPPEAR INTO A GROMMET IN A 'CHASSIS' MEMBER IN THE FRONT LEFT CORNER OF THE ENGINE COMPARTMENT. MY NEXT MOVE WILL BE TO RELUCTANTLY PEEL SOME INSULATION OFF OF THE FAN MOTOR LEADS AND CHECK THEM OUT, THOUGH I CAN'T BELIEVE BOTH OF THEM FAILED AT THE SAME TIME. THE ONLY PLACE I HAVE NOT BEEN ABLE TO TEST OR JUMPER AROUND IS THE POWER LEAD TO EACH FAN FROM THEIR CORRESPONDING RELAYS AS I DON'T KNOW FOR SURE WHERE THE LEADS GO AND THE COLOR OF THE LEADS DOES NOT MATCH THE WIRING DIAGRAM. ANY HELP WOULD BE VERY GREATLY APPRECIATED!!!
