My blower motor has been an op since last fall. I ran a power jumper wire from the 12 V battery up to the red green wire. Tested and blower motor, resistor and switch all worked. Then ran a ground jumper wire from the body into the brown red BCM signal wire. This wire energizes the relay. Blower motor was inop with this test. With this test, it tells me that the internal blower relay in the fuse block has failed.
I have great news. I was able to get a hold of a used fuse block, installed, and blower is back!
hope this helps others

Ok, the 30 amp fuse I circled is the blower motor fuse, but it looks like the relay is for the headlights.
Is the fuse ok? You should find voltage at both ends of the fuse, between the ends and a good ground point. (Key On)
Edit: apparently the blower motor relay has been relocated on the 2006 model and the Bentley manual doesn’t show that. I’ll dig around and see what I can find.
***Please Help** I've ran into the same issue with the blower motor, the motor has been replaced, I'm told the resistor has been replaced.. I'm not great with diagrams and would like to know it the RELAY is bad will I still get power to the 30A fuse????
The blower motor is new and I know it works, not getting power to the blower. I have power at the 30A fuse and I have 2.7 volts going into the resistor ( not sure if it's supposed to be low voltage).
