i installed a new window run on the drivers side today. this is the seal that runs in the window channel, around the inside. it was 90% easy but NOT easy to push the extended piece into place that goes down into the door. i had to use almost half a can of silicone spray and was pushing the seal, seated into the channel, down from above. i did NOT want to remove the window regulator, which may have made the job easier. if anyone has suggestions on an easier way, i am going to do the front passenger side too. on the plus side, i noticed a drastic reduction in wind noise and the window no longer rattles when the door is shut!
