Renault Laguna Dynamique Nav DCI 2006 - Heater problem - Osborne

I have a problem with the heater in my Laguna. The fan to the passenger side blows only cold air out, no matter what setting I have on that side, even when set to 26. The heater on the drivers side blows out heat correctly, although the fan runs constantly, possibly trying to compensate for the passenger side.

Any help would be appeciated.

Regards

If it's dual zone climate control, it sounds ike the control unit has failed. it could also be a jammed directional control flap buried underneath the dash.

Laguna mk2 are bad news, both electrically and mechanically, especially the diesel, think carefully before throwing lots of money at faults
