The recipient is a 1989 Ranger that was a 2.9/5 speed/4x4 truck. No power options except cruise. No AC.
The donor was a 1994 Explorer with a 4.0, auto, electric 4x4, and almost all power options. (PW, PL, power seats, and premium radio amp. No DRL or the Limited options.)
The Ranger received a M5OD and 1350 manual t-case during the swap.
The Ranger was stripped of all wiring except the tail lights, fuel pump and dome light. I used the Explorer headlight harness, dash, and dash harness. This was done so that I can have AC and not have to repin the Ranger dash cannon plug. I spliced the appropriate wires for tail lights and fuel pump and now I have a truck that runs...
... but the problem is that the heater controls do not work. In fact, the heater blower knob turns the dash lights on and controls their brightness. And when the "heater" is on, the indicator lights for the turn signals are both on and get dimmer or brighter but the blinkers function normally.
I'm not sure how to troubleshoot this. I have disconnected all of my spliced in plugs and gone back to how it was in the Explorer from the factory and nothing changes. I have gone so far as to pull every unrelated fuse, relay, and harness plug and the only ones that make a difference are on the heater harness - if I unplug the blower motor, resistor, or big pink/white wire, the issue disappears, but obviously the blower motor still doesn't work and the dash lights also don't work.
My thought here is that the blower motor relay is tied into the Daytime Running Lamp module (or in my case, the DRL bypass plug since it doesn't have DRL) through the purple/orange wire and thus the turn signals which is feeding back through the headlight switch plug and the dash lights.
Thoughts? This was all functional when I removed it from the Explorer... it is just so odd that is doing this weird shit now that it's in another cab.
FWIW I have tried a 1993 Explorer dash harness and have unplugged and replugged everything on the harness a dozen times or more and checked/recheck grounds with virtually no change.
