The other day after I drove home without the AC as its been cooler. I got n my 91 300TE the next morning and noticed my AC Blower didn't blow. I had replaced the motor and regulator last spring.

Today, I noticed that there was hot air coming through the vents, passively since the fan doesn't work, even if the thermostat is set to 65.

Does this sound like the "buttons" , anyone ever experience this ? I'm puzzled about where to start.

any suggestions/pointers/links to threads etc are greatly appreciated

Thanks
