I'll add my 2 cents also. My bottom driver heater went out over a year ago. About a year after it was replaced, so this will be my third heater. Passenger heater which gets more use is fine. 15 below in Chicago and the heater didnt work. Blinked a few times then went out. Once the car warmed up it worked OK.

Very long time since I've posted. Nice to see you all again.
