2001 v70 Fan Blows Air, But Not Hot On Passenger Side

Yeah, do the calibration. During calibration CCM perfoms wipe test and determines position of flaps.

I have the same problem on a 2006 S60. A/C runs cold only on passenger side but heat on both sides. Somebody suggested getting the climate control system calibrated. Would this need to be done if nothing was ever done to the system? What could cause the heater blend door actuator to become uncalibrated? Short of replacement, is there anything that can be done to cure a balky actuator?

After doing the VIDA calibration, I am no closer to finding a solution than I was before.
I still get air blowing on both sides, and A/C works fine on both sides, but heat only on driver's side, cold air blows on passenger side out of all vents, including the one in the center console.

There are no codes associated with the CCM, and the sensor is clean, I removed the CCM, and took off the rear cover with care, and cleaned and inspected the thermocouple sensor.

So, is there any sort of diagrams for the barn doors and motors? The 240s have such wonderful diagrams for everything, and the VIDA is occasionally very helpful, but most often not. I have looked at several videos on YouTube, and all have failed to clearly identify which motor would control "heat vs cold" for the passenger side.

I'll see if Alldata has a diagram later today

Any luck with the alldata diagram?

Air dist motor ECC

I'm still looking...

That's a big help in itself, as it clearly shows several arms per motor, and it implies that there is linkage that could be jammed, or broken or simply unhooked that would impair performance while escaping the notice of the CCM.

[richardgengle]

were you able to figure this out? if so, how?

[packetfire]

Sorry to be so long in reply, the motor linkages were the culprit. By disassembling both sides, and comparing the motion of each under identical CCM settings, the linkage issue was resolved. The L-shaped arms were the issue, they were not in their "tracks" in the disk that is rotated by the servo motor.
