Question about 2003 Jeep Grand Cherokee
Ok, so my 2003 Jeep Grand Cherokee is acting crazy. Some mornings when I put it in reverse or drive my lights (dash, headlights & parking lights) will make a clicky noise and flash on and off. At the same time, the alarm (the one like you left your headlights on or keys in the ignition) will keep binging.
One morning, it wouldn't stop and then after it did my windows wouldn't go down, the outside temp. gauge would read "--", my horn wouldn't sound when I locked the doors and the light's wouldn't flash when I unlocked them with the remote.
My boyfriend thought he solved it by plugging and unplugging these two wires that feed into the fuse box under the steering wheel, but unfortunately it still does the same thing.
How does car drive
do head lights work , not dim
is charge./battery lamp in dash cluster OUT.
tell all that works and not works
the BCM can not just be swapped. (needs programming)
sounds (me blind) like low system battery voltage.
even a bad battery , hark. can do that.
cant charge a bad battery we cant.

The body control module is the cause of your weird problems. Replace it.

You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)

Have you had your battery load tested & charging system checked? I'm suspecting your battery is draining down during the night, and if a battery is getting weak, the cold really takes it toll on it. A load test will confirm if battery is weak & testing alternator for charging, will assure that the battery is, or is not getting charged as it should. Having both tested, shouldn't cost much, if not free, especially from a parts supplier that you are considering buying parts as needed from.
