Welcome to the Forum Joanne :wave:

I suspect you have 2 issues with your heater......

The rattle is possibly a few leaves or other flora or fauna that have been sucked into the air intake and are now catching on the fan blades...

The fan stopping working can be a few issues depending on symptoms...

The flashing Mileage is often a symptom of low voltage which again can be a few issues... basically the car is nun via several computers.... these "talk" to various parts (called nodes) eg the speedo cluster.... If the Battery is a bit weak, the alternator is on its last legs or there is a dirty / bad earth (connection) it can throw the flashing mileage error on

Get the battery and alternator tested BUT DO NOT listen to the first place offering a free test get a couple done as too many see it as a open licence to rip the driver off (a Mate of mine ((ex HGV mechanic had a row with Halfords worker when he took them up on a battery test since they tried to rip him off for a battery, alternator and brake shoes)... we changed the shoes this summer :ROFLMAO:
 
Thanks for help. When i push under the glovebox the noise stops. so dunno if its leaves?
