Why don't my heater get hot

Will this help?


Thanks, this helped. The cardboard glovebox liner was in bad shape anyway so I yanked it and lo and behold there was the temp door lever. Turns out it was set on cold. I flipped it the other way and damn that heater gets hot. Nice to know that after 2 winters with no heat. Oh, well. Problem solved. I have no problem opening the glovebox to adjust the heater. Works for me!
