I have had this vehicle for three days and it is doing the following: 1.) No horn. 2.)No driver side headlight, No high beam auto, when high beam auto engaged the instrument cluster lighting turns off and no headlights. 3.)No windshield wipers.I am having that same problem with my 07 Grand Cherokee Limited.

funkymonkey. I have a 2011 GC Overland with 5.7L and tow package. I recently flushed the cooling system, changed upper and lower radiator hoses, replaced 203 degree thermostat with new 203 degree, new 18 lb radiator cap, and refilled with Mopar coolant. Engine temp has been consistent (before and after). The problem goes back in WK2s in the 5.7L Hemi to model year 2011 with the use of valve train multi-displacement systems. Needed a replacement engine in mine a bit over a year ago. Bob N. 2011 Grand Cherokee Overland 5.7L, 1999 Cherokee XJ 4.0L (off-road enhanced) Hemi tick finally cured. 76k on my Hemi and have always run full synhetic oil, changed it and used injector cleaner every 5k and only run top tier 89 octane, and the tick would never go away.
