No 4x4 Bad actuator and more.

Thanks for all the replies. I’m still missing 12v at the switch of the transfer case. I do have 12v on the pin 420 of the front axle solenoid switch and all switch are working, verified with a multimeter. Does anyone know how this circuit works and where the 12v comes from?

Well, I don’t have any blown fuses. According to the schematic, the 4 wheel drive taps off the a/c fuse. That fuse isn’t blown and does have 12v, but there is no continuity between them. Is there supposed to be? That’s good and bad news on the actuator. I’ll have to pick up a new one. Thanks...

I should clarify a little more. I used the socket to test the solenoid switch and the front differential engagement. The diff does engage with the socket and the solenoid switch is working too. Also, the transfer case is engaging because the front driveshaft doesn’t move when in 4hi (but freely...

It’s an automatic 88 k1500 with a shifter. The truck has 220k and the four wheel drive worked about 2 years ago (haven’t used it since). The transmission was rebuilt almost 2 years ago (4x4 worked after the rebuild), but the transfer case has unknown mileage. It could have as many miles as the...

Hello all, My four wheel drive isn’t working and the normal troubleshooting steps aren’t sufficient. I’m doing these tests with the truck in 4hi and the key in the on position. I have the two front tires off the ground. When in 4hi the front driveshaft doesn’t spin (back tires on the ground). I...
