Techguy Posted August 3, 2023 Author Share Posted August 3, 2023 Ahhhh, I didn't understand from your post that the bearings were bad. Just that "the blower motor went out". Then that you cut the connector off and couldn't get the new motor to work either.... This clicked in my head that it was not the blower, but something else (and that "else" can often be the resistor fuse, because people don't even know it's there!) ah no worries, still good things to check and i will. i apologize, my brain is running constantly (two full time jobs) so sometimes i dont convey things correctly Link to comment Share on other sites More sharing options...

You should have power in 'key on' or 'accy' at the brown/orange wire. The other wire should go to the resistor. Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted August 11, 2023 Share Posted August 11, 2023 blower so this one i found by mistake and its got the correct blower motor wire connections. but i cant find what application this would fit Given the D8UZ part number I would say it was originally designed for a 1978 Bronco. 💡 Looks like E-series vans up into the '90's..... Of course it may fit many models made after that. You have both the Ford # and the Motorcraft MM-381 numbers to go by. I'm sorry. My parts manual is on CD and I don't have a functional optical drive to look at it. Link to comment Share on other sites More sharing options...
