i just spent the whole day doing this... but i tore the dash out and the airbag. i didnt start out that way but i just couldnt get my fat hands in there so i just removed everything in the way. now that i know how it all goes together i think i could do this in 4-6 hours including pulling the dash up... but the dash was impossible for me to put back in with out removing the airbag.

looking for a B3 glovebox to go in airbag hole if anyone has a line on one.

***edit: user steve addy got me a glovebox, fits perfect and came with a key to boot***

unfortunately i needed to button it up and go home and i forgot something... my blower fan control doesnt work. ill have to pull the hvac controls again in the morning and fix it. pretty sure i just left it unplugged.

First of all a big THANKS! to diesel300dmanual and ToddA1 for pioneering this effort. Like others here, I was putting up with the marginal creature comfort rather than deal with a complete dash removal. But this procedure looked easy enough to manage. I took ToddA1's extra step(s) of removing the airbag, mount bracket and dash distribution plenum. One caveat here is that the top bolts on the air bag mount are not easy access and more than a little patience is called for. The real benefit of this method is the clear access to the repair area. With the distribution plenum out of the way, access to the foamless doors is clear and easy. And is sure is nice to have heat this time of year!

Well, I appreciate the props, but I in no way pioneered this method. I may have come up with the extra step to save time and effort, but it's truley a group effort.

Did you lift the dash? If so, the A/B bracket screws should be easy to remove either with a ratcheting box end or 1/4" ratchet and 8mm socket. I think I used the latter.

Going to tackle the blend door problem starting tomorrow. Probably use felt and Hvac tape. I didn't realize B4's came from the factory with heaters.

Not likely. The plenum is going to be different.

I just tried to do this on my A3 Jetta (97 model year if it matters). The knee bar/crash support has to come out to get the whole box unit out or even the front off to get good access to the doors. Getting the bloody bar off means getting the steering column off.

I was able to do this by getting the dash out alone and working from the top of the HVAC box, I'm "lucky" enough to have small enough hands to get in the hole and was able to use felt tape. The only reason this route worked was cause the tape was tacky enough to stick, but if it no so much that you couldn't peal it a bit if it tried to stick to anything you didn't want.

Also getting the entire door covered on 1 side was nigh impossible. So far I have a hell of a lot better heat than I did before (keeping in mind, I'm in Socal where we are currently "freezing" our asses off at post-50F temps).

Did VW decide to build this cars by starting with a heater core/hvac unit in mind and assemble around it?

Yes...yes they did. And I'd love to slap the engineer that came up with that stupid design, among others.

MB did the same thing with the W140 and that car is a lot more complicated than the Passat or Jetta. Having the evaporator replaced in that chassis is a several thousand dollar event.

I removed the plenum to get at the doors, clear access to doors, a layer of hvac tape then felt sticky over that. There is a easy way to remove the airbag. take out the bottom Phillips screws on the airbag cover, ( the front that should be a glove box ) then you can raise the cover up and sit in pass seat with a 8mm socket and 8" extension, 3 min job. No need to stand on head and work blind. Airbag will stay out, I used a 3.5 ohm resister in airbag plug, no light ! Thanks to all for the good info, nice to have heat !
