Four wheel drive lite is blinking and wont go out

If rear end is up in the air only. And it turns. Then know its not in four wheel drive. If u put the rear end up on jacks and leave the front end on the ground and then put it in four wheel drive its going to pull the truck off the jacks Danger. Does the truck try to come of of the jacks. If yes then its in four wheel drive. Should also be a lite on the dash. Saying 4 wd

I belive that it should stay constentley light. Try to put it into 4 wheel drive. Put it in reverse back up about 10' Put it back in drive and see if it works...Best of luck

Are they vacum operated or you have to lock it in by hand.

under the hood ,in the center of the fire wall is the relay that sound bad

it blinks cause u have problem .
and you have to diagnose to get the trouble code

Does the vehicle in gage into 4 wheel drive at all? You can tell by putting it in 4 wheel drive and see how it moves. You can feel the difference. Also it does sounds like a short somewhere in the wiring under the dash

small sylinoid on the top of the transfer case needs replaced. easy to do. it has three vacumelines going to it just trun out and replace like a bolt.

There is an electric motor that engages drive.  Mine was stuck and a mechanic beat it w a hammer while I was in vehicle w brake on in drive pushing the diff 4wd buttons.  It freed up and started working fine!!  It looks like a small starter under car on passenger side. Or buy one on ebay  for cheap and replace it

Push the "2 hi" switch while you're driving it.

You can do this while you're driving, as these systems have "shift on the fly".

You will hear / feel a "clunk" when the system disengages, and you will see the "2 hi" light come back on..

For a temporary fix so the car can drive, remove the fuse for the four wheel drive. it won't actuate the four wheel. The car is always in 2wheel drive. the fuse is located under the hood, the very right side of the of the fuse box, the third fuse up from the bottom. This can be checked in the owners manual. When I need four wheel dr I place the fuse back in. I haven't fixed the problem yet but can drive it 2wheel on the road. think it is the control module for the four wheel dr located under the dash board behind the glove box. Dealer part for $450, I would rather install and remove a 10cent fuse
