Service/repair manual for 97 Tercel to debug ventilation problem

I've been troubleshooting a ventilation problem in my Tercel with some garages (one being my regular mechanic, and one being an authorized Toyota dealer). They can't find anything wrong, so I'm experimenting with different things myself e.g. hosing down the intake vents beneath the wipers. I'm tossing around the idea of taking apart the dash to get a look at the heater core and the fan. I need to look at a diagram for dummies. I have a Haynes manual for '87-'94 models, but I don't find the diagrams basic enough. It's hard to make out the

3D view from a line drawing. The diagrams do not have nice shading to show the 3D, so they are hard to decipher. For a newbie like myself, it's mostly just faith and guesswork, which is somewhat troubling. Also, there are diagrams that show details about something but not the context, so I'm not sure where that detail is located. Furthermore, there are no manuals from Haynes (or Chilton) beyond the 1994 model. The Toyota dealer has a Toyota manual for 1997, but $140 (too much for me at this time). As well, I have such a manual for my former 1989 car; while the diagrams are much better than Haynes, it doesn't cover the ventilation for the passenger compartment.

Are there online sources of such information, at a more instructional level than (or at the same level as) in the $140 service manual? I tried to find the service manual at the municipal library, but they don't even have Haynes manuals beyond the one I have. And the reasons why I have the 87-94 manual is because I couldn't find one for 97 when I looked, years ago. I also phoned Toyota Canada, but they don't deal in such things.

Are you the same guy with the fume problem?? Maybe you should get a nice gasmask from your local US army surplus. Anyway.. try techinfo.toyota.com. Its a subscription service, and from what I've heard it's the same thing that we factory wrench apes use at the shop (Ive never used the public subscription version, maybe others here have add'l info) . If its the same as the dealer support, you will find the interface obtuse and idiotic, but the info in there is everything from the factory manuals & wiring diagrams.

Yes, same guy. A gas mask is a good idea, but it would cut down visibility.

The website looks. I wonder if the material is any easier to understand than a newbie. Specifically, the section about the ventilation system if any (Haynes & Chilton don't cover this, and neither does the service manual that I bought for my former 89 tercel). Any comments from current users?

In any case, I put my car through 3 car washes in the past few days. One is a drive-through. The other is a do-it-yourself, where I aimed the jet of pressurized warm water into the intake vents for 3 minutes. Each of these seemed to help, but after enough driving, the problem seemed to be the same. Not sure whether it just takes a sizable exposure time to be bothered by it, or if the fumes actually get worse with time. I think that some of the engine shampoo from my mechanic's cleaning got mixed in with the Krown antirust oil that coats everything in the engine compartment. So the shampoo residue doesn't just dry away. Instead, Krown "creeps" and delivers the shampoo residue to hot surfaces in a time-delayed manner. That's the only reason I can think of for why the shampoo smell lingers so strongly for weeks. It is suppose to be gone in a matter of hours.

I told my mechanic that I wanted to open up the hood an aim the warm water at the interior of the engine compartment. He says it's not very wise, and to cover the alternator & distributor with plastic bags before doing so. This would not be easy to do properly, since one of the two was tucked in, out of the way. Upon hearing this, I said I would ask a "detailing" place to do this, since they would be more experienced ("detailing" in this neck of the woods means non-do-it-yourself car wash). The place that's big on that here is Ziebart, which is supposedly famous througout Canada and States. Strangely enough, the Ziebart guy said there was no need to bag the alternator/distributor. His engine shampoo washes everything, but focuses on the sidewalls. It seems to help a bit at first, but after so many "fixes" that seemed to work at first, I am not easily convinced. If the fumes come back strongly, I will try to seek out a service somewhere that blasts the engine compartment with hot water, with the bags protecting the electronics.
