Blower motor gasket

[johnb]

Does anyone know if you can reuse this (late models)? I'm fixing my fan resistor wiring next to the blower motor and there's a lot of crap I'd like to clean out from around the blower motor while I have the cowl off. But I don't know if I want to remove the blower assembly and risk damaging this seal. The PET describes it as a "sealing cord".

It’s just butyl tape. Same stuff that the tail lights use to seal to the body. Around where I live, you can get it at autozone. It doesn’t harden or dry, so you may be able to reuse it, but it isn’t a guarantee.

Is it the same as the stuff used to hold the plastic cowl in place over the blower motor?

Honestly I’m not sure. When I removed mine, it didn’t seem like it was the same stuff. When I removed my tail lights, it was still pliable and tacky. Whatever they used on the cover seemed to have actually dried and was hard/brittle.

Yes, it really is the same sticky, black butyl rope that comes in rolls for installing windshields and such. It usually stays soft and tacky but will harden with age and weathering. I just replaced mine with some I had left over from an old windshield project on another car and it worked perfectly.

I used exactly this (3/8ths butyl tape) to reseal my old NA's blower. The original stuff looked to be the same, except where the seal failed (maybe I wasn't the first to remove the blower) and/or where it oxidized and hardened.

That’s the stuff I used too. It’s exactly the same as what was in my car and my box lid had never been off before.

Thanks guys, I got that stuff from Amazon. So anyway, here's why I wanted to pull the blower motor assembly:

Looks like the car is falling apart with rust, right? That's what I thought too. But then...

Tada! Gone. Years ago I had a really badly rusted battery tray and I had to get some serious repair work done there. The guy did some kind of media blasting. I'm not sure what he used, but it looks like a lot of it accumulated behind the blower and eventually turned into that rust colour. But it also hardened into these solid chunks that perfectly mimic a rusty body. A couple of minutes of gentle scraping and vacuuming and it's as clean as a whistle.

Next question: any suggestions for what to use to replace the foam around the evaporator? It looks similar to the stuff used to seal the intercooler. Years ago I replaced that stuff with foam tape, but it would be tricker to do a clean job on this with the same tape. If anyone has done this before, I'd love to know what you used!

@Tom What was it that you were using when you were R&R’ing your heater box during your dash swap?

I was thinking of using something like this for the foam gasket:
