Could that explain why on some very, very rare ocassions it smells like there is something burning when I put the heat ON. If I simply turn the heat OFF and then back ON again, the smell goes away - this does not happen often maybe 3-5 times a year. Since winters in NC are short lived - have not worried about it. On one occassion a year ago one winter, I saw white smoke coming out of the windshield ducts. I quickly shut the car off and pulled over. When I pulled the hood open, NO SMOKE, could not find where it came from and it the smoke was never visible again.

Is it OK to leave it the way it is, or can leaving it alone cause greater problems. What does the aux. pump do and how can that be the problem? My common sense tells me if the the heat works in LOW it should work in HI, just the fan blowing faster over some coils. Please straigten me out. Is this something that I can see on the CD Rom. Is this a typcial malfunction in the 300?
