The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.

In this video, we're going to replace the weather strip on this 1986 GMC Jimmy. This is kind of three videos in one. Broke the window on this Jimmy accidentally because I hadn't replaced the weather strip. You're going to see how you remove the window and replace the run channel weather strips and the ledge weather strips in and out on the door panel. The processes in this video is basically the same for all the '73 to '87 Chevy and GMC pickups as well as the front doors on Suburbans and the crew cab pickups from '73 to '91 and also the '73 to '91 Blazer in full sized Jimmy. The tools you'll need are Philips screwdriver, a window crank removal tool or two paperclips. For more information on the paperclip method, we do have a window crank removal video that you can check out. 5/16 and 7/16 sockets with ratchets extensions, pliers and two regular screwdrivers, small and medium.

Okay, you start by removing the door panel. We do have a separate video for the door panel removal. It's pretty straightforward. You'll remove 11 screws in the window crank or power window, unhook your power window and power door locks. This video is in two parts. Basically cover taking apart the door in the first part, part one and then we cover putting everything back together in part two. Just bear with us here as we work fast to get the door panel off and then we'll get to the information on the weather strip and window and stuff like that.
Okay, so to get the old track out and get the new window back in, you need to remove the triangle window which one 7/16 bolt here and then three Philips screws, one at the top and then another one here and down here and they go in this way. I'm going to remove those three screws and that bolt and then we'll pull the vent window out. Okay, after we remove the vent window, there is a 5/16 bolt right acted to that hole right there. Okay, here I'm going to try and get one of these screws out. What I'm going to do as I got a screwdriver in here, I'm going to take my hand and twist the screwdriver some and then I'm going to bang it with a hammer and the bang actually kind of loosens up the screw a little bit and the screw will start turning.

Okay, so basically once we got those screws all removed, we're going to do some tugging to make it loose. What you're going to do is as this weather strip is hard in this truck, it keeps holding the, It's hard and brittle, it's the whole reason my window broke. I'll pull it out in here. In fact, it's holding my broken window at the top, it's so brittle. Okay, as I fumble with this here, I'm just going to tell you that the best way when you pull this vent window out is actually once you get it down to kind of what you have here, you rotate the front of the vent window, the lower front as you would say towards the outside of the truck and there's a little bracket on it and rotating it that way. You'll see it when I actually put it back later in the video, that's the easiest way to maneuver rit.

Pull the crank all the way down. You'll have the crank down to give us a little room. We got to turn it that way to get this part out. I'm going to pull it up some more and the whole thing comes up. I took off the outer weather strip and you can see it's nothing but little clips that clip into these little holes here. You can basically just pry it out and pull it up. I did bend this a little bit so I'm actually going to take probably a 1/4"? extension and just kind of pry those back so that it's not sticking up as much as we are. I can probably show you what I'm talking about here. You see these little clip holes right about here, okay.

You can see they're actually bent out and it will good to have it all nice and flattened so I'll take a screwdriver or an extension and just kind of pound those and bend them back in so that when the weather strip goes on here, it's night and tight and fresh. You put the weather strip on here and most likely it's going to have a little gap right there because it's how that formed. Okay, now we've got the weather strip off and the vent window out. You then just crank up the handle as far as it goes and then push it back, out and up and off.

The last thing you got to do just to prepare the frame is probably on your old weather strip when you pull that channel down, there is that little pin that stay behind. You just want to reach up there with some pliers and pull that pin out. I'm just going to take this whole run channel weather strip which is dried up and fallen apart out of the old vent window. Okay. The inner belt weather strip from the door panel. Just pull it right to reach in there and pry it all through teeth. I'm not worried about my door panel. That's really the best way. I'm trying to pull too hard on this and you'll end up breaking the plastic and now you'll tap it so it rise up.

Okay, so now your door is basically taken apart. Please check out the part two video to see how you get it all back together.
