It reveals the elements of the circuit as streamlined shapes and also the power and signal connections between the gadgets. 2002 jeep cherokee wiring harness diagram schematics2000 yj blower motor resistor repair heater fan speed control chevyblower 2002 silverado tail light wiring diagram schematics2006 chevrolet schematic 2006 part 1 how to Options. Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life. Many Dodge forums tell of this problem. Good luck. The blower motor resistor (or final stage) varies voltage to the blower motor to achieve the desired speed. If your blower motor fails and replacing the final stage unit has not remedied the problem, the blower motor itself is likely at fault. Over time, a blower motor may become noisy as the motor electrical contacts wear. 3.Blower motor does not work on certain settings . Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. If the blower motor resistors’ internal components fail it may cause the blower motor to malfunction, or not function at all on one or more of the settings. It sends still-hot coolant back to the engine, causing temperatures to rise as the coolant fails to do its job of cooling down the motor. The cooling fans keep running. Conversely, the cooling fans may keep running even when the engine is offline. This odd behavior indicates a different issue in the relay that controls the fans. Yes, my e46 had problems with the blower resistor twice. No such issue with any BMW, including the F10 now, since then. But your description is exactly what it did on my e46 - lack of fan control speed - erratic behavior, up, down, all over the place. I found the place where the F10's final stage resistor is located. The final stage resistor controls the fan rate on your BMW X5 blower motor. A failed resistor is visible when your HVAC unit is stuck on one cycle or one setting. The resistor controls the motors speed on your BMW. The final stage resistor is usually what causes the air to either stop or work intermittently through your vehicles vent. have 2002 bmw x5 blower motor running with ignition off removed blower motor fuses fan stopped stopped . removed fuses battery still discharged. unplugged final have 2002 bmw x5 blower motor running with ignition off. removed blower motor fuses and the fan stopped running but the battery was still drained .
