seal came off both rear doors

You'll need to reinstall them or better yet, get new ones. I've found that gluing them is a big mess if it doesn't work. I think they're made to stay on without glue.

the best thing to use and the chepest is to use rubber sealent from your local car parts place works better then any thing and cost about 5.00 and get new rubber seal ez,if i can fix mine and iam a women any one can,if my husband can fix with remote he,d do it!!!!!!!!!!!!!!!.not
