I have a 2006 Jeep Grand Cherokee 5.7 liter Hemi. last 6

Customer Question

I have a 2006 Jeep Grand Cherokee 5.7 liter Hemi. For the last 6 months or so, every once in awhile all the dash warning lights come on, the headlights go out, the a/c and radio stop, then everything comes back.
Yesterday, I was backing out and it felt like I was in 4wd low, I then engaged the fwd low, and took it back out and now it says service 4WD system.

Good afternoon and welcome to JustAnswer!!

I would be glad to help you get it fixed if you can tell me what codes you have in the FDCM(Final Drive Control Module)... It could be a bad actuator in your front axle but the codes will verify that..

Talk soon,

Brad

The abs light traction control esp/bas lights came on together and the "service 4wd system" came on

sometimes on a hard turn it makes a clunk like the 4wd is engaged or when in reverse
