Default 87 Bronco XLT 5.0 4X4 Problems

I recently bought an 87 Bronco XLT and the 4X4 doesn't work, It has the push button 4X4. Any help with a wiring or any help?

I have a 2x4, so I haven't had to deal with 4x4 problems much. That being said, I see the have a lot of problems when the shift actuator. It either completely goes out, or you have bad connections going to it. When you push the 4x4 button does anything happen at all? Climb under the truck and look at the connections going to the transfer case, unplug them, clean them and plug them back in.

That's what I'd do to start, at least.

If it has the automatic hubs, if you don't have to manually turn them, they are notorious for failing. There are kits to convert to manual. Warn is a good one. I would follow Booba's suggestion first as it costs nothing and may fix it.

I have checked my wires and cleaned them and still nothing, I have planned on changing over to manual but first I want to figure out why it isn't engaging

Is the 4X4 light not coming on? There is an electric shift motor on the BW 1356 transfer cases. These motors are prone to failure. Check the relays and check for voltage at the switch and the shift motor.

No, the light uses to come on when I started the truck but now it doesn't come on at all and when it did it didn't feel like it was in 4X4

As far as the light is concerned, it could be just burned out, but I still think you should check for voltage at the switch and the shift motor. One or the other will tell the light to turn on. I'm leaning towards the shift motor to do it.

Does the 4X4 switch run through a computer or does it do straight to the transfer case?

That, I'm unsure of. I know the 97+ trucks had one called a GEM.

IIRC the switch on the dash is powered by +12V, and it just actuates the Transfercase Motor, no computer. It sounds to me as if it is the electric motor, IDK if you can do this on newer(electric shifted)transfercase's, there's a trick you can do to see if it's your transfercase itself or your hubs, put the transfercase in 4hi, climb under the truck, spin the front driveshaft left(towards the driverside)it should take no more than 6-7 turns and stop spinning, that'll tell you it's engaging, now if it's still spinning, listen near the hubs while spinning it, you'll hear near the back of the hub a "click" sound, the hubs aren't engaging.

But like I said, that's for a Manual Shift T-Case, haven't tried it on an electric shift one.
