Webasto Clicks then stops

[GregOConnor]

I got confirmation that the controller should be sending 12v to the blower motor and there are no safety prompts that change this. therefor it is safe to assume that the controller box has an issue. I would like to open it up and have a look just to see if the interior is damaged from heat or what. I also need to find a wiring diagram to see if the motor is fused after the controller or if the controller has a relay built in that opens the fuse for the blower. I see three fuses and only tested them all and never defined them. The Webasto parts list doesn't show how the motor is fused, it only shows several wire harness part depictions
I think the controller may have internal relays and that is all that may need to be replaced in these units?? Controllers with Webasto and Aquahot seem to be big ticket items that f'up often enough to warrant a little research here.
