I have a 1995 C2500 2wd Auto with the 7.4l. The blower motor will not run and the wiper motor will not run. As of today I’ve replaced all fuses, the blower motor, the blower resistors, and have ordered a new hvac control module. I’ve replaced the multifunctional switch and the wiper motor.
These two problems started after a mechanic shop pulled the transmission to replace the clutch plate.
I’m trying to find the exact wiring harness layout to figure out what wire:wires could be related to the 2 issues.
any help would be greatly appreciated

the multifunctional switch does function the blinkers and hazard lights just not the wiper motor. So the whole switch is not affected just the wipers.
thank you for reply

you shouldnt need a schematic. just look or run your hand around behind the engine and feel for any trapped wires or wires that could have been pinched
