Series I Laguna Heating - bobla
Hi, I have a series I laguna and the heater only blows hot air. Please can anyone suggest a good starting point to try and solve the problem? CHeers

If it is a cable operated air flap (diverts hot/cold air), the mechanism or cable may be broken. Turn the knob/lever and listen for any operating flaps. It's probably broken.stuck in hot position.

If however it uses a hot coolant diverter valve, I would take look at that. Dont know much about Lagunas in particular.
