Well, I am finally going to take the plunge and replace
the heater fan - I can't take the noise any longer.

I am looking for some input on a related problem.
When the heater control is moved to warm or hot,
anything other than all the way to the left, I get
full heat. I have to keep moving the temperature
selector back and forth from all the way to the
left and anything to the right to regulate the heat

Basically it does not mix cold air w/warm air
Is this a heater valve issue or is it a mixing door
problem? If I have to replace the heater valve I
guess I'd prefer to do it while I am replacing the
heater fan -but maybe it's not that big of a deal.

Thanks in advance for the help.
