Why isn't my heater working?

The heater in my Renault Scenic has stopping working. I've checked the fuse, but it's working fine. Any suggestions?

Have you checked the coolant level? When you say it has stopped, is that the fan motor (is it blowing cold air)? Check the heater pipes/hoses going into the bulkhead (to the heater matrix). See if they're both hot or if one is hot and one is cold. If one is cold then it could be that the heater matrix is blocked.
