Hi, I want to save money rather have garage to fix my fault blower fan. The problem is when I put my key on and start the engine, the fan is contine on low speed while the switch is off! I am not expert on electronics but it sound should be easy DIY at home, I have check the fuse is fine and the motor is working on all speed but be can't switch off. Could that be a resistor fault? Found on eBay for £55 is this right price seem too high for little resistor block under motor fan. My is climate control.

thanks
