A few weeks ago, my horn starting blowing without me honking it. It would blow for about 30 seconds, then stop, then about a minute later, start the cycle again. This happened even when I turned off the car and restarted it. The only way I could get it to stop was to remove the fuse.
Last night, I went to the gas station and went inside. When I returned to my car, the keyless entry on my ignition key wouldn’t unlock the doors, though it did make the lights inside and out flash, as usual. When I manually unlocked the driver door, I noticed that the interior light on the driver’s door came on but wouldn’t shut off, whether I was driving or had shut off the car. Also, none of my power windows are working, nor do the interior buttons on any of the power locks work. Also, I now can’t open my tailgate.
I did a search online as to what the causes may be. One thing I read said that perhaps the theft deterrent system got tripped somehow, either by removing the fuse for the horn or something else. I would think, though, since so much time has passed since the horn going out and what happened tonight, that those issues wouldn’t be connected, but I’m not sure.
Other than this, the car is driving fine and everything else seems to be working.
What should I look at first? I thought of checking the fuses, but I can’t find my fuse puller and so will get one in the morning.
Thank you in advance for your help.
