How to Check fan control module 2001 vw beetle? Power is getting to both 30A inputs but no output. In addition to both fans not working a/c clutch will not engage.

Over time the clutch does go bad or burnout so get the system checked for flow and pressure to ensure the compressor is working ffirstly then the check valve for blockage or if the system needs to be recharged...if all this checks out then you may need to have it rebuilt or replaced...oh and the seals too can cause a similar problem if they are stretched.

Replace the retarded ignition switch,the electrical part of the switch only if possible.

Bad fans are common. You can either turn the AC on to see if that will trigger them, or jump the thermo switch at the bottom of the radiator.

There is also a fan control module located in the area under the battery, but diagnosing this is difficult.

I WOULD CHECK FUSE -16- 10 AMP FUSE CHECK FUSE- 3 -30AMP FUSE AND CHECK FUSE - 8 - 30AMP FUSE CHECK ALL 3 FUSES THEY GO TO FAN CONTROL MODULE.I WOULD CHECK THEM FIRST BEFORE BUYING ANOTHER FCM. IF FAN CONTROL MODULE BAD YOU WILL GET A CHECK ENGINE LIGHT THE ECM WOULD WARN YOU ITS FAULTY.

check the ambient temperature swutch, wirings may cut or the sensor itself, located at the engine compartment, right side

ENGINE GETTING TOO HOT AC PUTS MORE LOAD ON ENGINE AND OUT SIDE TEMPERATURE HOT.YOUR CAR TELLING YOU I AM HOT AND NEED A BREAK.MAKE SURE COOLANT LEVEL NOT LOW AND THE COOLING FANS RUNNING WHEN AC GOING IF NOT CHECK FAN FUSE IF FUSE GOOD.YOUR THERMO SWITCH NOT WORKING OR THE COOLANT TEMPERATURE SENSOR AND FAN CONTROL MODULE COULD BE THE PROBLEM IF THE FANS DONT TURN ON.

WELL AC COMPRESSOR HAS TO BE WORKING IF YOU GETTING COLD AIR.YOU HAVE FUSE/RELAY BOX AT THE LEFT END OF THE INSTRUMENT PANEL ALSO YOU HAVE FUSE PANEL UNDER HOOD IN ENGINE COMPARTMENT ON TOP OF BATTERY.CHECK THE 30 AMP FUSES ONE CONTROL THE COOLANT FAN CONTROL MODULE IN WHICH OPERATES THE AC COMPRESSOR CLUTCH CIRCUIT AND AC PRESSURE SWITCH.

Sounds like the resister pack has gone bad. its located on the passenger side under the dash on the bottom of the fan housing.
