You are the worst!
LOL

 

Did the "over head module" get wet? If it got wet then I'd unplug it as my next step.

 

Thank you Lowrange2 for the diagram. I am unfamiliar with the "overhead module" or where it is located. (please...nobody tell me the obvious)

as you said...The horn switch was removed from the circuit, so no power from there...that leaves sticking relay, and overhead module I guess... going to check on those right now.

I just went over the jeep with a wet vac, and turned the heater on high for about a half an hour, I placed a house fan in the driver back seat pointing down on the floor, so the wind should be going under the driver seat up under the dash on the driver side. Driver side seems to have got it the worst. The dash was really wet this morning, but it was a hot day today. The floor on the front and rear driver side were still fairly waterlogged after work today. Passenger side floors seemed damp but mostly dried up. The module under the center console seemed free from any major moisture, but it is possible that the carpet may have wicked some up to that location. I really don't want to pull that damn thing. seems like a big pain. *whines*

 

I'd check the relay before you did all that. It's pretty simple circuit. Should be fairly easy to track down the issue. Let me know how it goes.

 

Downloaded the service manual, found the 01 specific wiring diagram, and did some checking. Long story short, after ripping half my jeep apart, and disconnecting a lot of connectors, I found the problem. It was the clockspring that shorted somehow. I am assuming from moisture. Disconnecting the horn switch did nothing, and neither did disconnecting the Keyless entry module.

Not quite sure how to dry it out yet, but at least the honking has stopped! Maybe I will try a hairdryer...now that I know where to point it.

PS, I did check the Relay first... Swapped it out with another one, and it did the same thing. It was pretty hot from disconnecting the circuit at the horns. If you ever need to disconnect your horn, pull fuse 21.

 

Cool. That part of the clock spring is grounded out... If you can get it to dry out without corroding you should be good to go.

Don't forget that side of the circuit is switched ground, not positive.

 

It's supposed to do that. It's to alert fellow motorists and neighbors of your coolness!

 

haha

 

Nothing to add here, but it sounds kinda funny that it stops for 10 minutes then it starts honking at you lol! Attention *****

 

If somebody left you out in the rain all night with no protection, you would ***** too I suppose...

 

This is probably too little too late but I'm putting in my 2c anyway...

Be patient with it. Go easy with the directed hot air application. XJ's have weak electrical construction (with crappy, unfriendly splice locations and such).

I've done a Jeepload of XJ electrical gremlins and, if I've learned anything about fixing them, I've learned to not force it. It only makes it worse.

 

Why don't horn/alarm malfunctions ever happen during the day? They always seem to go off in the 3am - 7am time frame, normally in a crowded neighborhood or campground.

My experience at least!

 

Playbass, you need to go farther away from civilization where there are fewer expletives per square mile. That's why you got the Jeep, remember? - jk -

 

I've been out there, man. The alarm alway works perfectly to keep the deer and bear from stealing my jeep.

 

I saw your post title and was going to post about your clockspring....but you already found.out.
