Looking for suggestions. 
I have a 1995 gmc 6.5 diesel 4x4. Everything will be working fine, then blower fan, crusie and 4x4 will stop working all at once and always together. Sometimes if I shut truck off and turn back on they will all work, but that works less frequently now. I have changed the blower fan resistor and the 4x4 actuator but same results- all will work or not work at the same time.
Any suggestions?
