Is it an easy fix as I’m not really a Mechanic vut I will try and do things myself so I don’t have to go to a garage that charge a fortune

Heating effect is not very huge so just unplug and tape/seal connector of the power cable. Pretty limited space to operate there...

See picture link I posted. Location of heater and its connector is shown. There is no how-to instructions for this, you need to figure out how to reach the power feed cable. Of course there probably is WIS document about replace the heater, you just not need to do that.
