I was trying to put new weather stripping in my doors. But I was having some difficulties with the door not closing all the way. I could only get one click on my striker before the door just stops and won't close any further. I then noticed the middle of the seal has a section that was melted/spliced into the middle of the rest of the seal. This middle section is thicker and stiffer rubber than the rest of the seal. At first I thought it was just a defect in the rubber. But I am now begining to think it needs to be timed on the door somehow but I have no idea how or if it is supposed to be timed.

Has anyone else put them on and had trouble? Anyone have any ideas on what I am doing wrong

Thanks!!
