I posted a few weeks ago about my problem with the A/C only working on the driver's side even with the temp control switch set to the lowest temp on the passenger side. Driver's side A/C is fine.

Since then, I have used a code reader from BSR in Sweden to read the DTC output and there were no codes saved for the ECC. I then removed the glove box and saw that there were 3 servo motors on the inner passenger footwell side of the ECC unit. The upper one controls a large white rotating disk that I assume is attached to the unit that distributes the air to the different areas on command from the control unit. I tried different combinations of vent settings and this control motor responded to each of them. I also tried heat and cold and found that the lower left motor responded to this and I assumed that it was opening and closing a vent to allow heat into the system. I could not see any evidence of movement of the motor on the lower right but there wasn't anything to see moving so I don't know how significant this is. I am not sure it is the vents but I thought it might be. Does anyone have any info on the ECC that might help me with this?

Thanks in advance for any help.
