BMW Repair: air conditioner, center vents, 1999 bmw 328i


Question
1999 BMW 328i e46.  The upper left and left center a/c vents blow cool air. The air from the upper right and right center vents does not cool. Air flow seems equal from all vents.  Any ideas of the cause?  Thanks for the help.

Answer
assuming that you turned the temp down on that side, i would suggest that you have a problem either with temp sensor on that side or the heater core on that side has hot water in it. The only way to be sure is to have the faults and diagnosis requests checked on the system.
