We have a base model (no AC, no options) manual 1997 Toyota Corolla that we are trying to keep alive long enough to teach the kids how to drive with a clutch.
Whenever there is airflow into the cabin (passive or with fan on), the air is hot. I'm assuming this is engine heat, and perhaps some baffle that is supposed to direct the air on a non-heated path has failed.
Are there any other likely explanations? And either way, what are some fixes I may be able to attempt?
Thanks in advance.
