1982 Frame Off Restoration

Now that you have the HVAC box out, I would love to know if it is possible to cut a rectangular hole In the face of the box facing the passenger seat vertically above the drain tube somewhere so that the interior could be accessed and vacuumed out right where the drain tube connects inside. If you could cut a rectangular hole, you could save that bit and put it back in place with foil tape.

Take a look and I would love to know what you think or if there is anything in the way inside that would prevent this from working. I would like to clean out the inside where the drain is but I don't want to remove the HVAC box.

A rodent chewed on this damper.

All of the dampers are rusty and the sealing gaskets are junk.

I marked where things went as we took them apart.

The evaporator has this fancy double-layer screen on it. Seems a bit overkill to me. I'm not sure I'll necessarily put this on the new evaporator.

I'll check. This reminds me of Suzuki Samurais. We used to be into them. We've owned 12. They had the same issue of crap going in through the exterior defrost vents and getting stuck in the HVAC box. And rodents of course.
On those you could take a hole saw, 3" if I remember correctly, drill a hole in the right place, vacuum the box out, then install a 3" plug. The whole ordeal took less than an hour to do.

That would be ideal but maybe even only a 2" hole would be fine

I carefully cut the nut to be able to remove it.

Tam blasted the rusty parts then we primed and painted them.

I'm really not understanding this screen. It appears to be on the downstream side of the coil. All of the nasty crap was on the inlet side of the evap coil. I'm really feeling like the thing to do is install a screen under the lower windshield valance and remove this one.https://uploads.tapatalk-cdn.com/202...3ed329d116.jpghttps://uploads.tapatalk-cdn.com/202...b47c09c8fd.jpg

Yeah a couple years ago I replaced the cowl and added a stainless intake screen. Seems like cheap insurance if nothing else. The cowl is kind of a pain to remove, needing to remove a few screws that also have to be sealed with RTV so they don't leak into the interior. https://uploads.tapatalk-cdn.com/202...3a7e4bf8af.jpg

Andy, that looks exactly like the mesh screen I recently installed. As you mentioned, cheap insurance.

Yeah mine was broken so it is already removed. I'll definitely be cleaning down in there then putting a screen over the opening.
