Question about 2008 Jeep Cherokee Grand

1 Answer

Battery electric/electronic problems.

I have a 2008 jeep grand cherokee which is parked always outside. I had a lot of electric problems such as:
- loss of memory on front seats and radio configurations,
- windows which do not slide and shut,
- centralized door closing which does not work...
- etc.
More recently, I could not start at all (after a long rainy week end). Went to Jeep, they changed only the battery. 6 days after, red battery alert and strong burning smell. Jeep changed the alternator. One week after, same failure. Could not start the vehicule, no electricity. Went to Jeep a third time, Jeep noticed a flat batterry but no fault. So they are stuck. On our side, my spouse and I only notice the failure to happen after long weeks of continuous rain, and pretty high degree of humitdity..
Any idea of what could happen?

1) Electrical problems are part of the Jeep heritage. The **** engineers have been ignoring the problems since the 1990s.
>>>> 2) Honestly, the idiots at the dealer probably ignored a very COMMON problem - the Ground cable. Remove it from battery AND most importantly where it screws onto insider fenderwell. Use soda water, bicarb, and Wire brush to remove the white fuzzy corrosion. Reinstall and dust bicarb on top of the battery. Spray WD40 on battery post conectors and the fenderwell connection BEFORE dusting with the bicarb.

2001 Jeep Grand Cherokee - Security Key Flashing/ Wont Crank after dead battery

A flashing key symbol normally means an invalid key. Do you have an other key to try? That all the gauges stay at 0 seems to point to a PCI data bus problem. Was the jeep parked outside or at least standing in the rain? Many times water ingress in connector C200 up in the passengers footwell area is the problem. The connector must be removed, cleaned/dried and reconnected. Ofcourse the source of the water ingress must be found, which many times comes from the windshield.

We had a similar problem with our 1996 Grand Cherokee. I don't know where it's located in the 2008 but there was a relay behind the glove box that was causing the problem with ours. I hope this helps.

Electrical Glitches?

Check to see if the Battery is close to 3 years. Batteries of Jeeps tened to not last more than 2-4 years. If the battery level is below 14V, you can have issues. Look at replacing the Battery.

Grand Cherokee Interior lights stay on

I don't know about the remote hand held key problem but concerning the light staying on...Try... turning off the rear dome light by pushing up on the fixture... it may have been accidently activated when loading stuff in the rear.

The rear dome light has a option feature that allows you to turn on/off interior lighting while loading cargo at night.

Good luck
