Hi,

I have got a strange problem, the complete heating system sometimes works sometimes not.
For instance, I take the car in the morning, switch the heater on and it works, I drive to the supermarket, come back 15 min. later and the heater doesn't work at all. The same happens vice versa.
I mean, the fan always works but not heating is coming out, only cold air.
I have also tried the air conditioning and got to the same result, no heating coming out.
It is really strange because it looks like a contact that allows it to work or not according to the moment.

I really don't know where to start to look at, can you help me in detecting the problem?

Thank you
Alex
