Heater display comes on. When you use the fan control from low to high it clicks but the fan does not run?

This could very well be a bad blower motor. The click you are hearing is most likely the relay for the blower motor fan.

Thank you for your help. I should have checked the connection. Which I did at the back of the heater control. Now is working fine.
