Hi everyone...was hoping somebody could help me out. Last night was driving and i lost the sound from my radio, was still gettin power just no sound. If i put the truck in neutral, radio would work, in drive it wont. Then 2 minutes later my horn went off continously until i pulled the fuse. But when i turned my headlights out, my horn would stop, turned lights on and horn would sound. Then got home and my lights wouldn't turn off at all. My cruise control isn't working either. The today was driving and my window washer pump started squirting fluid for no reason, until i turned my headlights off then the pump would stop... Has anybody had this problem or can somebody shed some light on this??? I dont want my truck to go up in flames !! It's a 2004 Ford Ranger XLT 4.0L

 

This sounds like a weird short to me. Possibly a clockspring or something is going bad but I've never heard anything like that so I make no promises.

 

I turned on the Lights and the F***** Horn is blasting 5:30 a.m.
in the morning. Try disconnect the pos. battery cable for about 1 hour.
Hope this helps.....

 

I have disconnected my neg, i will disconnect my pos.....Now could this be a problem caused by change in weather? Could this be a relay? Multi-function switch? How did you correct your problem with the horn?

 

THE MIST or The Snow....LOL
All I did to the Truck is disconnect the Positive Battery Cable and let it sit
for about 1 hour and reconnect it. No problems after that.....

 

How weird I have the same problem today. Went to get into the truck, turned on my lights and the horn starts blasting and the washer squirter starts going. Turned off the lights and everything stopped, but the parking lights stay on and don't turn off. My cruise control hasn't worked for awhile, and my truck is a 2004 was well! Did you find out the problem yet!!! Funny thing is I pulled a couple of fuses this morning to see if that was my problem on my non op. cruise control ( I replaced them), and now I have this trouble tonight. I'll try taking off the pos. battery cable to see if that works... fingers crossed.

 

Well it didn't work for me, after a couple hours with the pos. battery cable off. I even removed both cables and left them off overnight... still no luck. I guess I'll make an appointment with the dealership.

 

Just a follow up... My problem was solved, the dealer had to replace the fuse box in the passenger side kick panel. Water had leaked in and shorted somethings out!!!

 

Happened to me this morning, the horn and the lights anyway. Of course it was 5:30 in the am and I was in a neighborhood. Its been raining hard for two days, I probably got water somewhere it shouldn't be. How much did it cost you at the dealership?

 

Anyone figure out the problem? Today I was 5 hours into a 6 hour drive and the sound to the radio cut out. When I put the truck in park, or neutral, the sound comes back on. I was driving through some extreme storms, and I am pretty sure something got wet. I checked all the fuses inside the truck and everything seems ok. Guess I'll see if I have the same problem in the morning. If so, I'll pull the battery cable.

 

Reading the posts above, it seems that at least one person had water in the Smart Junction Box under the passenger side kick panel. Others seemed to be wet weather related as well.

I would pull the cover and try drying it out. Be careful poking around in there since the SJB is powered from some high current fuses under the hood (disconnect battery). Then you need to find the source of the water leak. Could be a windshield seal or cowl leak or maybe a door seal leak.

 

just a follow up. I did nothing to the truck, just let it sit over night, and the problem was gone in the morning.

 

Did anyone ever find the cause for the leak?

 

Found the problem, water somehow got into the fuse box, used the leaf blower to dry out the connection and wire brushed out corrosion on the connections, all good now!

 

I have this problem today.
Did anyone ever figure out where the leak was coming from?

 

Anyone figure out what leaked for this problem?
