I have a 1998 Transit traytop with air conditioning and in the last warm spell I noticed that the air from the centre vents and passengers vent was 6 degrees C but from the drivers side vent was 26 degrees C so I guess the vent is not adjusted correctly.

The system was re-gassed recently and checked out OK.

Does anyone know if I need to remove the dashboard to find the adjuster for the vents please?
