Cabin pressure vent

[BrianF]

Any of you gents know the part number for this vent? On my standard wheelbase 2006? Mine has been leaking for a few years, unless you have positive cab pressure, it would allow dust to get sucked inside. Bits located underneath the rear bumper, driver side. The flaps on mine are warped and the frame partially broken away from rock damage.

It appears to be 4 little locking tabs to secure the plastic vent to the metal ducting. The tabs are internal with only one accessible through a drain plug.

It looks like I will have to break it to remove it so I would like a replacement on hand. Anyone know any part numbers by chance?

Is THIS the *OEM Critter* Part (with P/N and Image...)

@mrrsm that particular part is incorrect but, that link got me further. Quarter panel vent is the correct name. So far, part 13588034 appears to be correct. Looks right as well.

That doesn't seem to be the right one. Fitment says it's for 2021-2026.

And I can't find it for our TBs. Probably discontinued new. Might have to find a good used one.

Moose, the one I found says its for 2002 to 09 and then the new models.

Tomorrow, if i remember, I'll call the dealer and see what they have to say.

Indeed I was wrong. This evening I got some time and popped the vent off. It is GM 15189391. Mine was, well, well used.

And of course it's NLA from GM. eBay was of no real help as I only found one in Lithuania .

I do have 3 TBs and 2 Envoys in my local Kenny-U-Pull. They don't list this particular part so no idea what they would charge. In any case, shipping would be cheaper than from Lithuania.

Another option may be to find a rubber flap material and replace it in your vent.

 

[BrianF]

Yeah, Internet was not much help. When it opens today, I'll call the dealer but I plan on finding a flexible, heavier material to glue onto the flaps to straighten them out and weigh them down.

You might consider something like a bicycle tube rubber as the material... maybe

 

[Mooseman]

Or large rubber patch material. I would just replace them.

 

[BrianF]

I will see how that material is fastened on and if its reasonably easy or non destructive to remove it.

Rubber inner tube might be a good move. It has to be somewhat heavy, flexible but rigid enough to keep shape.

Update there gents. The plastic retaining straps are press fit and pop right off. This means I can repair the thing again....

The factory material is thin, dense foam like. The closest thing I had on hand was that thin foam inside a socket set. I cut some peices out, test fit a bit and set them in. I was going to uses some milk jug plastic to partially cover the back but appeared not necessary. The foam is much more rigid than the thin factory stuff.

I used some days off silicone to seal off the sides and ensure the retainers do not back off. Its white trash ut thats how I roll!

 

[BrianF]

Also, I called the dealer. Part discontinued, no new crossover part and nothing anywhere in stock.
