I've had to do quite a few repairs this winter on my 94 F150. I've replaced radiator, water pump, thermostat and housing, heater core, upper and lower radiator hoses, heater hoses, front brakes, front rotors, front wheel bearings, starter, serpentine belt, smog pump delete pulley and idler pulley. The next ongoing project is how to get my 4x4 working. Push button, nothing. Have power going to switch and replaced 4x4 actuator. Is there a simplistic systematic approach to tracing the problem?

 

Send me a PM with your email and I'll send you the schematic and diagnosis.
