My baby's too cold
After taking part in the 19.7.00 diagnostic thread it's been determined that my thermostat seems to be stuck open; operating temperatures never get higher than about 85ºC as opposed to the 97ºC or so that it should be reaching. I'm already familiar with this issue and I think I know everything I need to know to handle it... I only bring it up because it let me make a clever thread title.
My baby's too hot
This is what I actually wanted to ask about: I rarely use the climate control system with A/C on. When I do turn A/C on everything is hunkey dorey and nicely cold.
But, when I go back to bypassing A/C and I just let the vent fan blow, lately I've been getting hot air out of the footwell and windshield defroster vents, even with the temperature set all the way down and the center vent dial turned to full blue. The air coming out of the main vents is just slightly warmer than ambient, and it gets hotter if I raise the temperature setting or turn the dial toward red. So, I have some control over the temperature of the main vents, but above and below seem stuck on 'hot'.
Is there a separate blend door that might be stuck, or what sort of condition do you guys think could cause something like this?
