Let's have a little contest here. I'll describe the problem and you see if you can correctly diagnose it. My X5 is at the dealer right now, so I should know the fix later today.

Situation:

A/C only blowing cool air and not cold air out of the "left" vents, while it is blowing warm air out of the "right" vents. Temp controls on the left and right side are set to 70 degrees, outside ambient temperature is 100 degrees. Final stage resistor was replaced about a year ago with the newer unit.

My X5 is a 2002 3.0i BTW. Thank goodness I have an extended warranty with Warranty Direct, so this will be my first claim with them. This will also be a good test to see if WD is worth their weight in salt .

If you have had this same problem, what was your fix?
