I am having a problem with my door chimes constantly going off when the door is closed. I also am getting the driver door open message but the door is clearly fully closed and locked. In about a 5-10 mile drive it probably goes of 20 times. The dome lights are also staying on as if the door were open. I installed tow mirrors about 5 months ago and this problem started about two weeks ago. The truck is a 2009 ECSB. Any ideas why this is happening? Are the door panels not triggering the pin showing it is closed? Any ideas would be appreciated.
