Heater Box

[DieselSlug]

Hello all,

Was wondering if there is any way (minus ripping the dash out) to fix my heater box? This was broken before i bought the truck and i don't even know how it happened. I never did figure out a way to permanently fix this. My defroster doesn't blow very hard, most likely due to the fact that there is a large hole in the box. I get complaints from the passenger and I am still cold. As my temporary fix i keep slapping duct tape over the holes. But the duct tape only lasts a couple weeks before the heat dries up the adhesive surface of the tape and it falls off. Any ideas? Thanks!

Like it says, anything but duct tape.

You could fiberglass it, but what a mess and time. Pulling the dash and doing it right would take about a full day. This includes pulling the donor from a parts truck.

I would use the aluminum tape to bridge holes. If you get the right kind (made for ductwork) it sticks pretty good. I use it all the time on bath fan ducting

I had fixed a heater duct on my '69 dodge back in the '70s with foil HVAC tape. The fix outlasted the heater; when I replaced the core and ducts in the '80s, the original duct had disintegrated inside the foil tape but it wasn't leaking.
