security horn/lights going off randomly

[mjollnir79]

I have a 2006 ion 100000. I've had this problem for awhile, it used to happen about 5 years ago when i'd open my door. with the key(fob stopped working) This resulted in me removing the fuse for the horn.

I dealt with no horn, but then I had to replace the drivers door due to an accident. I got a salvage door and obviously installed it myself(kind of a no brainer). I thought now that the fob works with the new door, I could put the horn fuse back in.

Everything was fine for awhile. Now it goes off randomly, pulled the fuse again to prevent annoying neighbors. And then now it is to the point of killing the battery(which is about 5 years old btw).

I do not have a sunroof, googling showed me that was the issue for some. I also left town for awhile with the keys with me so the fob was far away from the car.

Any fuse I can pull? I tried disconnecting the wires that connect the fob from the door, no luck.

Any ideas? any temporary fixes?

Replace the driver's door jamb switch. Unplugging it is the equivalent of leaving the door open. You can connect a jumper in the plug temporarily to see if the problem goes away if you like, but I'd just go ahead replace the door jamb switch because they are so cheap.

Could I just tape it "closed"? I noticed the past is cheap enough not to justify a salvage yard, which is what I usually do.

No, if the circuit doesn't already close now when you shut the door, it certainly won't close if you tape the pin in.

You must disconnect the harness from the switch and install a jumper to close the circuit. You may find that the plug is very corroded and may need to be repaired/replaced.

You could try shooting silicone spray into the pinhole of the switch to buy some time before you can get a new switch, but it sounds like the switch may be too far gone for that.

Just got the new switch, installed it, and 5 minutes later it started doing it again. I'll try maybe the passenger side one and see if it helps. It's draining my battery down to nothing every time. I have a second car I'm using though, so it's not rush rush but still annoying!
