The 4x4 in my 98 expy has stopped working so today I started to check some of the electrical. When I check the dash switch plug there are 4 circuits. The first is 12v hot when the headlight is on. The second one has 4.95v. The third shows ground and the fourth shows ground when the headlight is on. No matter which way I turn the switch there is no output on the third wire. Is this correct?
Does anyone have the wiring schematic for a 98 4WD system? The problem is definitely electrical as this happened during a Florida downpour. The lights on the dash started flashing and the relay kept clicking and after about 10 minutes it stopped. The self diagnostic lights still come on when I start the truck just like the airbag and check engine do. Any help would be greatly appreciated. Thank you
