Another weird electrical problem...one headlight won't turn off

[tleisemann]

This might be the last straw for me with my X5, but I thought I'd post here bc one (of many) previous problems was solved easily with a member's help. I don't know how this is connected but I'm sure it is in some way...

Sunday night when driving home I had the heat cranked and seat warmers on. It was starting to get hot so I turned the heat down. Next thing I know the temperature was displaying as celsius instead of fahrenheit but seemed to be stuck on low. I have no idea how that happened! I fiddled a bit with it before allowing my passenger to do the same, all to no avail. Was almost home so figured I'd worry about it in the morning, if it didn't reset from having the car off overnight.

This morning it wouldn't start..clicking but that's it. Seems the battery is dead. Didn't have time to deal with it then, but tried to jump it just now. No luck, possibly bc the jump car didn't have enough power to get it going. Figured I'd call AAA bc they got it going for me before. Then I noticed that the driver side running light was on. The switch is off, and key out of the ignition, but it stays on! The only thing I could do to turn it off was to disconnect the battery completely. If I reconnect it just goes back on though!

Any ideas???
