Anyone else having problems with the back door weather strips coming off at the bottom? We live on a dirt road and when dirt builds up on the lower portion of the weather stripping, it pulls off and flops down. Our body shop guy says he sees many Edges come in with that problem. He says its a Ford engineering issue. Also, somewhat related, is how much dirt or snow and ice build up under the doors, covering the flat edges at the bottom of the door and along the threshold. Anyone figure out how to remedy this issue? The body guy says even if you replace the weatherstripping, it will begin to happen again in a not too long time period.
