Renault Laguna 2004 Heater/Blower not working & Reverse Lights?

I have a 2004 Laguna and the blower has just stopped working and so has the reverse lights. The only fuse i can find is a 20amp fuse that operates the Air Con (which seesms to be ok as i have swapped it out for a good fuse. The Air Con lights come on and so does the rear demister any ideas?
