This morning I started my 2002 Audi A3 and the turn lights, wipers andair con are not working. The car is working well except for those 3 problems. I checked all the fuses and they all seem to be in good working order.
I know you say that you have checked the fuses, but have you actually tried replacing them? Sometimes it's hard to be able to see the cracks.
If possible you really want to get VCDS plugged into it as it should give a specific fault code to the problem.
