On my '87 300TD, factory alarm. Seams that the alarm won't turn off from the drivers door since we had the Ice storm and single digit temps. I can still turn it off from the passenger side though.
I just figured that it could have gotten moisture in there and frose so it wouldn't make contact. But, I am unfimiliar with what makes it work in the door. Is there anything I can spray in there to loosen it up, or is something just broken? Any ideas???
