Ventilation - Warmer air on driver side

[petrsol]

Hello, 
I have Berlingo II B9 multispace 2009 1.6 HDI 66 kW with MANUAL A/C .  
I quite tired from troubleshooting of this issue and I disassembled half of my car dashboard and checked gears and plastic parts but it seems OK but..... 


Issue:
On the driver side vent output, I get significantly higher(5-8 C) air temperature than on the passenger side. When I turn on A/C It decreases the temperature but driver temperature is still significantly higher. 


Do you any idea what could be wrong with it? 

thanks

Welcome to the forum. That's an interesting problem, I can't remember anyone having that problem before. Have you checked the pollen / cabin filter?
