What is the part that in a Ford Ranger 2000 that initiates 4WD. I can't get my drive to turn on. But once in a while when it's really warm it will turn on.
truck this past winter would not initiate 4WD. When I move the switch over from 2wheel to 4wheel nothing happens no light, no changing I can usually feel it switching too.
However this summer for fun I switched it over and it did turn on and the light turned on too. I took it to a mechanic and asked his opinion he wanted to charge me just to look but he thought it was electrical.
There are two modules in the truck as well as relays in the
relay box. Also a shift motor on the tcase. Any ofthese could be bad or inoperative. You will need to go step by step to try to find the cause. Have a pro run a scan on the system to see if there are anycodes.
