Replacing Vent Window Glass (Only)

[BGBronco]

I need to replace my passenger side vent window glass. It works fine but has some pitting / etching. I obviously need to purchase new glass but I'm wondering if I need to remove the overall window frame or if I can cut out the seal, slide out the old one, and install the new one. Thank you.

I just put some in and I think it would be near impossible without taking the vent window out of the door and glass and surround out of the vent window frame. Glass is sealed in with window packing tape. I had to heat and cut the old tape and tap out by knocking the lower edge of frame off glass then working glass out of longer side part. The frame has that crease allowing it to bend down but looks like it would break if you moved it back and forth too many times. Then get new tape and using soap and water press it back in to the frame. I pressed long sideof glass in first and then pushed the lower side back up on the bottom side of glass. Its also good time to replace the L shaped pivot pins on the bottom of the vent window as I bet at least one of yours is probably broken or rusty and about to break.

Just did mine also, hopefully you might get lucky and the window being so old, might just fall out. Ditto on Hotrodjohn's method.

The frame might come out easily if needed.
Take off the inside door panel and take out the window stop on the bottom of the inside of the door and have the window drop below the seal. That should give you enough room to get the vent out. That is how i put mine back together also all together. You might want to replace some of the vent frame parts while your at it, fairly inexpensive.

I just did both on my sons bronco. I used a window deglazer. It kinda looks like a pizza cutter but the cutter is on a 90 degree shaft with a countersunk rivet holding it on. This is so it can be flat on one side. Put some liquid soap on the glass and place blade against glass and push into the seam as you roll it like a pizza cutter. It is how commercial windows are replaced. Took me about 5 mins per window. Then to reinstall new glass get some vulkem from building supply store. Fill channel up about half way and press window in place. It should squeeze out and leave a bead. Close window and latch it. Let dry overnight and take razor blade and run down window frame and then scrape towards frame and excess comes off. Very clean and easy. Don't get vulkem on hands. It looks like black caulk but it takes mineral spirits to take it off skin if it is still wet. If it dries on skin you have to wear it off. Don't ask how I know that
