Just this morning about 3 minute after starting down the road, I notice heat in the V50. The temp is set for 70 degrees on both sides. However, while the left side is still blowing AC, the right side is blowing smoking hot air. AC off and on, fan off and on, adjusting desired temps had no effect. Can anyone point me in the right direction as to what to look for as a possible cure?

potential fuse issue?

Maybe the interior temperature sensor is dusty, so it's not reading correctly? It's right behind the floating center console. Just get down there and blow the dust off of it. I did it in my XC90 the other day and it made a big difference in the ability of the auto climate control to adjust...

Verify interior temp sensor is clean and you may need a CCM software upgrade. Have seen the SW correct strange bugs like this before. Also it may need to be checked for damper motor codes which it may require a damper motor calibration. Code would be a configuration fault in the CCM if that was the case.

Take it to the dealership, there is a software update for this http://********************/smile/emthup.gif

Strange that after 36K miles and 4 years of flawless operation, that it would suddenly need a software update. I'll look around on the insides before possibly taking it to a dealer on Friday. Thanks for the ideas.

lol i know i said the samething!! It actually happened to me around the same milage as you. I just took it in and they said they updated the software and readjusted the flaps and no problems since. All for free

Thats the problem, over time the damper motors get wacked out and need recalibrated which sounds like they did. Although we dont actually no what the CCM upgrade fixes it has fixed a lot of problems.

That used to happen to me...

All i did was if it was blowing hot on cold settings, switch it all the way to hot setting, turn car off, then turn back on and back to cold.

Going home last night and back to work this morning, the AC worked fine on both sides. Gremlins.......are gone for the time being.

I checked this out on my 2009 V50 yesterday when I took delivery and have a similar issue.

Right A/C on full Left heat on full right side blows full force and very cold but the left side blows very weak and not hot, reverse the sides and everything works great as you would expect it too. If I turn down the left side heat the fan speed increases as it approaches the right side temperature setting.

I did notice is my menu there is an option for recalibrating the fans and dampers though so I think I try that and see if anything changes.
