  • The 4 wheel drive switch tells the VEC- Vehicle Information Center - weather you are in 4 high or 4 low.
  • It's on top of the transfer case between drivers side from and rear doors.
  • The VEC has been know to cause this problem to so if the switch does not fix it then the VEC might have a loose wire or be malfunctioning. The VEC plagued the Grand Cherokees for a few years.
  • This is a dealer part.
  • Also check the transfer case fluid level while there. Pull the top plug and fill it until the fluid just barely seeps out.

Regards, Tony

    The transfer case is the middle gear box under the truck. When you put the truck into 4 wheel drive high or 4 wheel drive low the transfer case [transfers] power from the rear and shifts it to the front as well. It basically engages the front wheels when 4 wheel drive is engaged. That switch is malfunctioning and telling the VEC you are in 4 wheel drive when you are not.

SOURCE: service 4WD switch

Need replace it; the switch is on the Transfer Case.

In order to get the correct switch you need to determine what type of transfer case you have. You can do this by crawling under the vehicle near the middle and look for a small round metal tag mounted on the back side of the transfer case. Once you have that number (new process type 231, 242, 249...). If your local jeep dealer is of a friendly sort you may even be able to avoid all the crawling around and just tell the parts manager your VIN# and he will be able to tell you what type transfer case you have - provided that it is the factory installed original.

Hope helps.

Will not go in to 4wd mode at all and service 4wd light is on

Problem is in electrical control.
1. check computer codes.(turn ignition 1 click ON/OFF) do this 3 times quickly leaveing ON. Then read codes by odometer.
2.Check 12v power to 4wd switch at dashboard and tranfer case.If there is power to transfer case the control is bad. Check gear oil there may be a sensor stopping it.

Volt gauge reading low but still charging 14.2 volts

the low charge # @ gauge could be caused by bad ground or high resistence in the wireing harness. Don't think it has anything to do with your 4x shifting prob I would check 4x switch and electric motor on transfere case.

My "service 4wd" came on and my push button 2wd,4wd, auto 4wd lights are this expensive to fix?

You definitely need to have it serviced & checked out...The service 4WD indicator read across my screen, but I did not have serviced...Eventually, I heard a grinding noise & because I didn't have it serviced when I took it in, it was found that the transfer case had no tranfer case fluid at all...This damaged the transfer case which had to be replaced (used transfer case-$400.00)....The transfer case is part of your transmission...The shape mine was in could have broke my transmission...Have it taken care off before it gets too bad...You must use only GMC Transfer Case Fluid

Service 4WD light illuminates on the dashboard message box

this is most commonly a electrical problem, does the speedometer read out correctly? if not it may be depending on if this is a Autotrak model, one f the two speeed sensors, or the acuator on the front diff, put the truck in 4wd, check the front dirveline to make sure it is engaing, if not your problem is in the t-case, if it does then move to the tires, if they are not engaged you have a problem with the actuator.

in most cases i have found the actuall 2wd 4wd switch to be the problem if you find that the switch is acting slow or you need to select the gear a few times before it shifts, then replace it these are very faulty
