Back at it again with the #260z#hvac#blowermotor this time. Note the type of material they used in the 70s, it appears to be resin! Wow! Transparent too! That's trippy!
A big plus to using resin? It doesn't fuse itself to the shaft of the motor! So removing it was as easy as remove the nut, washer, dampening rubber washer, then using two fingers to pry at the bottom and 'pop' goes the squirrelly cage :D
The blower shaft is splined rather than flat-sided like most modern cars do, which also may have helped with removal.
If you're driving a ~2011 Ford Expedition or F-150, and your blower motor suddenly stops working, after checking the obvious fuses and relay, check the wiring harness connector to the blower motor resistor. Most of them have way too much play and start to lose contact causing:
1. An open in the circuit
2. An intermittent open in the circuit
3. Arcing producing excessive heat
4. All of the above.
This one had it all. Pin #2 in the harness (yellow wire with blue tracer) was extremely loose causing it to bounce around on the contact melting the area surrounding it.
This Expedition received a new resistor and updated Motorcraft harness connector. Problem solved. When available, I always use OEM electronic parts. The closest Motorcraft resistor was days away... My guess is this harness and connector get kicked a lot. When I sat in the passenger seat my toes were only about 3 inches away from it when my legs were out forward and not flat on the floorboard. #Ford#Expedition#Blowermotor#wiringharness#connector#resistor

We Have Boost!
We have been quiet but were back with a new set up.
This chassis is capable of significantly faster passes and our new motor set up will get us there. This motor set up will be pure violence. Ya we know its an "import" but we think the blower makes up for it.
