Headlights pop up for no reason
Hi Forum. I have had no real problem with my pop up headlights since buying the car about 1.5 months ago. I know the passenger side gear needs to be replaced but waiting for Florida 90 degree/95% humidity to go away. Last night we got about 3.5 in rain in about an hour. I saw that the headlights had popped up and were on. I went out played with the switch and got them down. However they kept popping up, sometimes with no headlights on, sometimes 1 headlight on, sometimes 2 headlights on, and once the headlight with the good gear popping up by itself. I know a bad gear can cause the to pop up occasionally but that shouldn't have anything to do with the headlights on off or either one on or off or independently. I am waiting for the car to "dry out" to see if it goes away but thought I'd ask you as well. Any help would be appreciated. Thanks

You have a GHOST in the system.
One thing that can command stuff to function on its OWN is the BCM.
If the car was out in the rain, you could possibly have a wetted BCM. The BCM does NOT do well if its wet/damp!!!
Look inside the passengers foot well and see if its wet or the carpet underlayment in the foot well is damp.
Next is a faulty multifunction switch. It could be going bad.

Thanks for the info. The battery actually died when they popped up again while I was out. I recharged the battery and it hasn't happened since. Unsure if the BCM reset when the battery was dead or whatever got wet dried out but not happening now...
