Question about 1997 Jeep Grand Cherokee
I have a 1997 Jeep Grand Cherokee (4.0L). I purchased used about a year ago. Randomly at night the factory anti-theft alarm system will just start going off. I'm not really sure if it actually arms because it does nothing but lock and unlock the doors with the key fob. It doesn't honk or flash parking lights when the vehicle is locked or unlocked.
The only way to really describe the issue would be if you pressed the panic button on the key fob. It basically does this late in the night on its own. I have not noticed this to happen during the daytime hours.
This all started first when the interior lights would come on by themselves, the horn would be going off (like when you press the panic button), and the display would show that the rear hatch was open, but it wasnt.
I then came to find out that the battery began leaking acid and was very weak. I replaced it and the hatch open display went away and the interior lights didn't light up on their own anymore.
I thought this was just a battery issue because all problems went away for about a month.
Now just the horn goes off randomly at night. No other issues though. I hit the unlock button and it will go off. It might do it one more time at night after that, then that's it until the next night.
Just a side note: It does this on cold nights it seems.
Replacing the ECU will not require Dealer Intervention Although most folks Like to Buy them From junk yard, I Have Never done That For My Personal Cars or most Customers , as You May Buy the SAME PROBLEM & or More different ones. AND that Solution I would ONLY resort to If,, You have EXHAUSTED "ALL" other Avenues, such as Bad Dome Light Buttons, all it takes is 1 to be Slightly Dirty at the Contacts. I would check them all and there plugs/Connecters etc.I think I'll Do a little more reserch on this
But if I have Helped More or solved this Please Remember to RATE me Thonk you RejakWilson
