swingate problems

JEEP(just empty every pocket) i bought my 02 liberty and its had its share of issues but today it wouldnt crank. battery dead. i charged it and figured out it had a short. when i put the battery cable on i hear a noise like the lock in the rear. will i have to replace the whole assembly? i know somethins wrong back there because lately when i unlock the doors and get out to open gate ive had to turn around and go back and unlock again to get gate open:shrug:

Are you still on the original factory battery? If so, replace your battery. If you do a search for battery issues on this forum, you'll find a large number of electrical gremlins that live in the KJ when the battery is old... even if the batter is still "technically" working.

ok crabby mr wont be back

i had the same problem when my jeep battery died. i replaced the battery and everything was all better. yello is right most electrical gremlins are from the battery. i drove my jeep all day then stopped at a gas station turned it off came back out and the battery was dead and the gate made a strange noise. i replaced the battery and it seemed to fix it.

now remeber next time you post that there are lots of people and this forum that just look and learn. not everyone has the answer. its tough to be a mechanic and fix things over the internet. so slow down and realize that you are giving vague info on a holiday weekend. not a lot to people sit in front of their computer all day. some of us go out and use our jeep what they are for on weekends.

hope that helps

I agree, check the battery first and get a load test done on it--Autozone will do it for free. It's the easiest fix anyway. If that checks out, then you'll have to start digging into pannels and prying plastic...

The next thing I would check is that rear latch/locking mechanism. Try simply hitting "unlock" once, and if it doesn't work, check to see if there's anything causing it to hang up or whether it's even still lubed. Those little motors aren't really that powerful.

Failing that...then the connectivity fun begins...

I'm one of those that read your post because it was new, but didn't leave an answer because, frankly, I had none. However, after thinking on it a day or so here's my shot...

I agree with everyone regarding battery caused problems (my 2007 went all weird when the battery died after a cold night because the phone charger led's micro power draw kept the danged computer on even with the key off - dopey design.) Here's the rub: (and points to the overdone Government rollover safety feature of latching the rear gate when in drive, then re-latching even after hitting "unlock")...the auto-latching feature is built-in, with the only override option being to disconnect the lock connector. That said, your battery may be flaky enough that the computer module wants to latch regardless of whether you're in Drive or Park...it might be confused. :shrug:

If the battery is good I would try disconnecting it for a few minutes to reboot the computer then see what happens. If not maybe there's a correlation to the shift lever position sensor.

Of course, the other option is someone is messing with you and hitting the lock on the other keyfob when you aren't looking. :laughing1:

The rear sensor switch on the hatch handle would not release the glass hatch on mine and would randomly short out and release the glass while in park.

16 - 19 dollars at the dealer, 10 days to deliver for me since i've ordered it.

If it still operates the glass when you use the fob but not the handle, then i'd put money on the switch.

New battery couldn't hurt either, mine has never worked better since I replaced mine last month.

i finally tracked the gremlin down with alot of patience it was the body control module i could put the post on the batt and see there was a short and after pulling each fuse out one by one several months ago the wiper had started working like there was a ghost in it and it quit the bmc cured it
