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

2007 jeep compass 4wd light flashes overtemperature code after changing front wheel bearing


How tight did you make the nut holding the bearings onto the spindle? Did you change the bearing races too? Recheck the torque values to see if they are correct. an old race on a new bearing will cause temperature problems.

My 98 trooper doesn't seem to have four wheel drive, the dash light blinks, but it doesn't seem to spin all four in the mud so I can't tell if its working, does this light just blink? Or should it stay...


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

FRONT WHEEL LIGHTS ON DASH ARE BLINKING. I DO NOT KNOW WHAT THIS MEANS


That means that the four wheel drive unit is trying to engage but is'nt doing it. There's a switch on the front axel that indicates weather it is on or not and if the wire were disconnected or broken it'd do this too. moving the vehical very slowly backwards on level grounf in neutral and pushing the engege and disingade buttons you might get it to shift back into two wheel drive.

Two years ago my four wheel drive stopped working. I wasn't using it at the time and the dash light came on...and since then it hasn't worked. Just wondering what the problem might be?


i had a problem with the four by four light coming on all the time. I would shut the vehicle off and the warning went away. Recently I had the bearings and tie rods changed on the two front wheels, and now the four by four light does not come on anymore. Not sure if they are related, but it seems to have fixed the warning light. You might want to get your alignment checked and if it keeps going out, then it may be loose tie rods. Hope this helps.

4 wheel drive wont swich back to 2 wheel drive


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
