Xantia Turbo CT heater on all the time

[peters2718]

My 1997 Xantia Turbo CT with climate control has the heater on all the time. Possibly no problem in the UK but definitely a problem here with temperatures pushing 40 C. Could be an actuator problem or a control problem. Does anyone know whether the actuator, which I assume controls a flap which directs air from the heater matrix, is accessible without removing the dash, which I am reluctant to tackle.

If I remember correctly, the heat flap servo is mounted on the left hand side of the box near the firewall, just above carpet level.

I think that one of the mounting screws might be difficult to get a tool onto.

If you can get a Lexia onto the car, you should be able to check the operation of the ECU and the flap motor
