I have a 98 Cherokee. The battery will get low and when opening the door, the locks will constantly click. I replaced the window motor assembly on the drivers side. While I had it apart I resoldered the connections on the switch panel .There was cracking in the connections and when finished, it functioned correctly. I've seen countless threads in forums that address the fact, the right switch is the actual control of the system. If that switch is faulty, can it cause the battery to drain? Can it be the cause of the clicking as well? Is there a way to disable the lock system and manually lock? Thanks

 

Check the wiring inside the boot between the door and the body for breaks. Sounds like one of them has rubbed thru in the door somewhere, or in the kick panel. I 'think' you can just unplug the door lock actuator if you want manual locks? I would still check the wiring inside that boot, tho. But dont cut the boot. Push it into the door to get to the wiring.

 

I checked wires, found nothing. I replaced the switch in the passenger door and it still does it. I did a parasitic draw test and it shows .010 ma draw . Tested battery and it shows 12.65 v. and no issues with the alternator. All are fine. Any suggestions, other than pushing it over a cliff? When the battery is fully charged, there isn't a click. When the battery is low ( drained) i still get the constant click. I have unhooked the wires to the back hatch, as that seems to be where the noise comes from. I'm at a loss

 

Check your grounds.
