Electrical woes

Came home from out of town to find a dead battery and a sopping wet passenger floorboard (dangit, I thought I fixed that).

But the main issue is some electrical wonkiness. When I turn the car off, certain things continue to run. The AC stays on and the overhead console lights stay on. After turning the ignition off, I can hear some buzzing electrical shorting going on somewhere under the passenger dash.

Is this enough info for a forum post, or should I just bring it to an electrical professional?

f you just want to poke around and maybe happen upon the problem, take the passenger side kick panel off and check for water.

if you dont have/know how to use a meter, you're pretty much hosed. i can post up a bunch of diagrams, but if you dont know what they mean, it's futile.

I do have a meter, but my meter knowledge is very slim, and I don't have a ton of time to learn right now. I was out of town for 3 weeks when this happened... Most likely the AC evap drained into the cabin and shorted something which turned on the AC/lights/dash and drained the battery.

Very frustrating, considering I fixed the AC drain last month, which *should've* fixed the water issue. (I cut the hole in the wheel-well and everything)

Pull the PDC and check for water behind/in the PDC (fusebox). It seems only 3 other people and I are the ones to have this problem but take a look and see. My Jeep did some weird stuff after I shut it off as far as keeping interior stuff on.

mykey... you mean the junction block in the cab or the pdc under the hood? the pdc isn't generally susceptible to water unless the engine pukes.

Yeah, the PDC. The power distribution center under the passenger side kick panel. That's not the PDC? Fusebox maybe? I dunno. Water gets in = bad. That's what I know.

the one under passenger kick panel is the junction block. it's a sub station, so to speak, of the PDC.

Taking it to the mechanic. If water mucked up the electrical, I don't know where to start. This AC drain water issue has turned out to be the bane of my existence.

Why dont you take off the covering and allow air to dry things out, pour water into the vent at the windshield base with koolaid so you can see the color flowing, wrap the stuff with plastic bags once ithas dried - ride on.
