Technical Heater and radio not working after jump start

[HE646876]

Hi, had a look using the search function but couldn't find any similar problems. I recently left my car sitting for a few days and when trying to start it the battery had died. Jumped it with some cables and it was fine. About 5 miles in to the drive to work the next morning, the radio and heater both cut out. The heater now does not work on any setting and the radio has no sign of power getting to it! Don't think its the fuses as I tested them out.
Any ideas as to what it might be?
Thanks!

Still sounds like a fuse..or a wiring fault in the dash..

Yeah it was pretty much, just had another look at its the relay which has burnt out, cheers!
Any idea where i can get these cheap?

Breaker is cheapest..

Few days should not have flattened the battery.
Check the voltage at the battery terminals before the first start of the day. It should be 12.6 Volts ideally. Check it when the car is running. It should be about 13+ at idle rising to a max of 14.4 at 2000+ rpm. Overcharging boils batteries, blows bulbs and sends too much current through relays.
