Hello,

What does the temperature of the car thermostat get to & have you checked the relays, the power at the over head control panel & followed the power cable down?

If your engine, is warming up, as above. Then your duo valve is sticking.

It's located on the engine bay, left hand side, near the bulkhead and looks like two cylinders.

Re the ocp, you will need to check for power at the module, if present then the module is probably faulty (usually from water Ingress from the sunroof)
