The blower motor connections are the first thing I worked on when I got my TJ in Jan of 2019. I redid the fan switch wires, the 3 pin connector wires, and blower motor relay as the harnesses for all of these had melted. Once I got the fan running on high only, I moved on to engine, tranny, brakes, suspension etc... and moved the HVAC system to the back of the list
Well I'm finally coming back to dealing with the HVAC system. I have ordered a blower motor, resistor, and resistor harness. I am at a point where I can roll the dice and swap the new resistor harness for the old melted one and install the new blower motor and call it a day or I can add relays to remove the High current going thru the switch.
I think I have it figured out option 2 and it would be about an additional $25-$30 job from here and maybe a couple of hours of work to do it right. I've already opened it all up so the toughest part is figuring out where to mount the relays.
Please take a look at my diagrams and let me know if you think I missed anything.
