You will, probably, need to change the heater blower switch (around £14) which you access by removing the stereo and then the cowling. Note that you will need to get yourself a set of star screw drivers to replace the rear mounted switch. I did this a year ago the garage wanted to charge me £90 for a 30 minute job. Can you help, I need to find the infamous heater resistor; (the switch is fine, the relay and fuse look okay but the fan does not work at all) to see if it has melted the connectors.
