How to replace a car blower motor resistor UK

To replace a car blower motor resistor in the UK, you'll need basic tools like a screwdriver and the new resistor part. The blower motor resistor controls your vehicle's air conditioning fan speeds and typically fails when you can't adjust the fan speed. For UK motorists driving popular models like the Vauxhall Corsa or Ford Focus, the resistor is usually located behind the glovebox. First, disconnect the battery, remove the glovebox (if necessary), locate the resistor on the air duct, disconnect the wiring harness, and replace it with a new unit. However, we recommend having a qualified mechanic perform this job as it involves electrical components - improper installation could damage your vehicle's wiring system. Most UK garages charge between £30-£80 for this replacement service.
