horn wolnt stop

Thanks to good ol' Oregon weather and a leak somewhere I think I have an electrical short due to water, I just dont know were. I've got a 2000 f250 and last night as I was sitting in my living room I heard my Horn go start blaring, not honking but staying on continuously. I tried to use my key fob to stop it but no luck it just stayed on until i turned my truck on, I eventually just pulled the horn relay and it went off. I put the relay back in this morning and it was fine until a while ago when it happened again. I also noticed that when I lock the doors with my fob the dash lights will blink like my marker light do. any thoughts?

The GEM module got wet , Do you have a leak in your windshield? the GEM is on the pass side under the dash.

where is the GEM located specifically, I do in fact have a leak and i can see dripping on the passenger side. If any body has a picture of the GEM for reference that would be great.

From: Da UP, eh!
I just had the same issue happen on my 2000 F-250. I pulled the fuse for the horn and it of course stopped. That day I saw water near the E-brake handle and hood release handle, so I assumed water got into the fuse panel. I put the fuse back in after getting home and it went off again for a while then stopped. I pulled the fuse again and went to bed. The next morning my batter was dead. Jumped it and kept the fuse out, went to work. At the end of the day, the battery was dead again. Same thing this morning. Got to work, put the fuse back in, and the horn went off again about an hour later. I did not look to see if water was coming in on the passenger side as this thread suggests, but it definitely was on the driver's side. If you say it is the GEM module, is that something you can pull out, dry, then replace? What is the fix?
