C5 Heater Won't Provide Heat...!!!

[hamster99]

Hi

When I started my C5 this morning my heater wouldn't work, it flatly refused to provide any heat whatever setting I put it on. I have the dual climate controls and even when set to high it still only provided a nice blast of cold air. I have checked coolant levels and fuses and connected it up to the lexia but nothing showed as a problem. It was fine yesterday!

Any thoughts? Is there a thermostat or temperature sensor somewhere which might have failed?

The flap motors strip the gears and they get "stuck" in whatever position they were last in as the motor drive just spins in the rounded hole. One side of mine does this. Could be that though I'm not sure if both would go at once.

I have a C4 Picasso 1.6HDI/2007 (with Climate Control)... simillar problem but, I'm only able to vary heat & airflow from windscreen vent, not the other vents. So I suspect that the servo/motor operated Flaps have stuck or the output gear has stripped. I do have the repair/modification Kit P/N 1607044080 for the servo's but am having difficulty identifying the various servo/motor locations and as most of you can agree the dashboard panels with press-stud fitting are a nightmare to fathom ( always a risk of damage)... can any one please help.
