Air Con Fan

Post by chingdevil »

This might have been asked before but I can not find it.

I have a 2016 C4 Picasso Diesel, this started yesterday.
If my air con is on the fan will run full speed, even though the auto button is illuminated so there is no control. If I turn the engine off the fan continues to run and the car will not lock, if I press the minus button for fan speed and reduce the speed of it the air con is then off. I can then turn the engine off and lock my car the fan runs for a while after that but then stops.
Any ideas where I start to look for the problem are appreciated.
