Hi Has to be volt meter time. See if you have power at the fuse? (fuse 10 40amp) if not try swapping the blower motor relay with on of the other. Are we talking variable fan speed control or manual 5 speeds?

 

well havent used the volt meter but i have switched all the fuses and relays in the fuse box but its a digital controler so i guess that would be variable fan speed

 

HiWhat about an LED test light? This would make it even easier. The 3 wire plug on the module you changed Pin A is BK/OR wire is the Earth wire. Pin C DB wire is your feed from the relay/fuse. Pin B DB/LB wire is your speed control. Check for power and earth on A and C first. If ok on pin B if you have an LED tester and you probe the wire with it plugged in it will flash at different speeds as you turn the fan switch. All very easy to test.

 

thanks for your help beacuse of this test determined that it is the blower motor now just need to replace that if your know how could u please post a simple how to
