I am here, what did you find?
OK, both sides when it is plugged in?
OK, then we need to back up, I am sorry I misread your reply.
So at the DEF fuse in the underdash fuse block you have power to both the contacts on the back of the fuse with the key on? You did have the key on and the blower control on high when you checked the motor?
The fuses in the juncblock have labels, should be on the cover of the block. The DEF fuse feeds one side of the blower relay but go back and check the motor connection first with the key on and the blower on high. Look for any burnt connections along the way and let me know if you power to the connector and out on the pink wire with the motor plugged in.
That is fine, post to this thread to get back to me, I plan on being here tomorrow.
Yes, you can use a heavy gauge wire to jumper the relay, you will have to install the jumper each time you run the car and remove it when you are done.
The DEF fuse feeds the relay so maybe the ground for the relay is not present to turn it on.
The relay has a electro magnet in it and closes the high current side when it is grounded so see if the new relay works but if it does not I can help you check for ground.
Let me know what i can do to help
