Vw Fan Control Module Diagram General Wiring Diagram While the fan control module (j293) is dumb as dirt, it does monitor amp draw of the a c clutch (n25). if the draw is out of factory design (open or short circuit), the fan control module (j293) can cut power to the a c clutch (n25). a c clutch (n25) should be about 4.5 ohms. boostedgli, hmc, boki ar and 5 others. do not ask questions here!. To test a fan motor, unplug the electrical connector at the motor and use fused jumper wires to connect battery power and ground directly to the fan. if the fan does not operate, replace the motor. 2. if the motor tests ok, check the cooling fan thermo switch, located at the bottom of the radiator on the driver's side.
Vw Fan Control Module Wiring Diagram Wiring Diagram And Schematics For those looking for this info later, i mapped out the connections from the vw wiring diagram. for me my fcm was part number 1j0919506h. this confirms the differences i was seeing with my 10 pin fcm, in particular the primary 12v power going to pin t4 4 (whereas 14 pin fcm have 12v power at t4 1). hope this helps someone else. Unplug the ambient temp sensor and short the connector, then idle for 2 minutes and try the ac again. the sensor is located in the driver's side plenum under the rain tray. check continuity from the connector to the fcm if you've got time. here's the full fcm pinout. Whether you’re troubleshooting or modifying your 2000 vw beetle’s fan control module, having a detailed wiring diagram to reference will make the task much easier and more efficient. with the right resources and information, you can confidently tackle any issue that may arise. radiator fans not working when a c is turned on. Also pics to help you locate components, and the aplicable wiring diagram. the connector is a three wire, red, red yellow tracer, red white tracer (ground). you need to re read, i think your unplugging the harness (not harnesses) from the wrong component. you want the harness plug on the radiator fan thermal switch, not the fan control module.

Variable duty cycle signal from the instrument cluster j285 when the engine is not overheating, 0% duty cycle when the engine is overheating. use the vas 5051 dso to read this signal: 5 v div, 100 ms div. note: when overheating, this signal will switch the a c compressor off and switch the radiator fan to 2nd speed. t14 14. The 2000 vw beetle cooling fan wiring diagram consists of four main components: control unit, coolant temperature sensor, radiator fan and relay switch. the control unit sends a signal to activate the cooling fan when the engine reaches a certain temperature. the coolant temperature sensor measures the amount of heat and sends the input to the.
