Does yer AC vent droop down or fall into the outlet? Here's what I did to fix one on my 1996 T-100. I removed the vent module using a butter knife to gently work the vent module out. ;)

On the sides of each vent module are little tensioned pivot bumps that keep the vent from moving from their adjusted position. The tabs will break over time and give you the droopy vents syndrome. If the broken tab is still attached or intact, you can JB Weld a small backing to it and make it perform like new again. ;)

Broken tab...


Scrap piece of metal


JB Weld to the rescue!


New support fixed into place


Like new again!


Make sure you allow the JB Weld to set up properly or you'll be doing this job again. ;)

I know your post about the loose vents is dated, but i'm catching up, and that caught my eye. Having that problem, I pulled them to prepare to use your method of repair. Oddly enough, those tabs are completely intact. I did notice that the holes for the side with the fat tab seemed to be missing an insert. I couldn't find anything remotely close to a picture of the register assembly, so I had to come up with another fix. My bizarre way of thinking rose to the occasion. I had some old PC parts in a drawer with small rubber washers that I could fit right over the tab. When I put it back in, it was no longer loose. I still have you to thank, however, for that post which is obvious that it will work. Kudos to you, sir !!

The tabs on my vent modules had totally broken off, and I broke another one that I got at a junk yard when I was installing it, so Bam's JBweld method probably wasn't going to work for me. That old plastic is too brittle to mess with.

Instead, I decided to try jamming a 1/4" dowel into the hole on the left side of the dash vent to hold up the plastic vent module a bit. I wouldn't call it good as new, but it is definitely better than before when it was just flopping around in there.




1/4" was the smallest diameter dowel that my local Ace had in stock. 3/16" might be a better fit if you can find one, because I had to put quite a bit of effort into jamming the dowel into the retaining hole. Not sure that is ever coming out! If it does, the hole is probably a bit bigger now than it is meant to be, and I am not sure if a vent module with an intact tab would even fit snuggly in there any more.

I like to think that the wooden dowel pairs nicely with my Toyota Oak interior ;)
