"Hot air on driver side vents - Cold on passenger side" How do I get to page 5 to access posts #63 and #72The "low freon" speculation...needs to be investigated. I suspect the cold air coming out of the passenger side is plenty cold, which would not be possible with a freon leak.
Before bringing it into the shop, check out the driver's side air mix motor. This has been an issue with previous model years - if the air mix motor is the issue, it can be fixed in 15 minutes for free.
I don't have enough points to paste links...so use the odyclub search box and search for "Hot air on driver side vents - Cold on passenger side" and read posts #63 and #72 on page 5 - the latter is mine.
Awesome, thanks to all who have contributed to this thread! My 2007 Odyssey EX-L had this issue and I fixed the Motor Assembly part with a simple adjustment...
