Recently bought a 2003 A6 2.7 Quattro and I'm experiencing a problem: When the outside temp drops below freezing, my lights, blinkers, wipers and heater motors don't work! When its warm, everything works fine. Any thoughts as to what this could be??? Thanks

 

Has anyone else ever experienced anything like this? I am thinking it is a computer issue due to it affects the same things every time and it is not a random thing - it happens the same way every time... I would be curious to hear from others on this site. Thanks
