I have a 99 Ranger supercab 4X4. The other day the 4X4 was working fine, but today when I crank it up, the 4X4 high and low lights flash for a few seconds then go off, and the 4wd doesn't engage. I unplugged the connector for the electric motor and couldn't get any current on any of the prongs. Any suggestions?

 

Sounds like a short to me. I'd start by checking all the wires.

 

Here's an update. I left it in 4 wheel high for several miles, and the light finally came on and it was fine. I turned it off, then on for several days and no problem. Now it doesn't seem to want to come on at all and flashes 6 times, then goes off. Could these six flashes be a code of some sort?

 

mine does that when my switch is unplugged, usually when i have the dash out and im driving the truck. It could possibly be that your switch has gone bad.

 

Flashing lights usually means its stuck between shifts.

 

When you say between shifts, do you mean 2 wheel high and 4 wheel high?

 

Yup.

You can pull the shift motor and turn the **** with pliers. If your worried about it.

Otherwise cleaning it or replacing it are your options.

The brown wire needs to be removed from the connector. It just clips in, and will lock back in place.

 

Thanks for the info. I'll take a look at the motor. Heard sometimes you can tap on the motor and it may go in 4 wheel drive. I'm probably not that lucky though.

 

My 99 had bad vacuum lines to the hubs. After snipping the ends and putting back on the light stopped flashing and the front drive shaft engages. I am still engaged in the hubs, so I am going to replace the entire line on each side and if that doesn't work off to the hub mod or replacing them both.

the selector disk with the little contacts gets worn with use and stops making contact properly. Thats why I'm pro-manual transfer cases
