ok so i just boughta 99 audi A6 quattro from a great dealership, the front and rear fogs do not work, whats the problem? the lights on the headlight switch dont light up eitherim guesssing a fuse? and where these would be ? also i have one switchblade key for the car and they are buying another one for me from an audi dealer.. the keypad magically started working last night after i replaced the batteries and then i went out to the car this morning and it doesnt.. what happned? how do i get it to work again .. one more thing is i put in a aftermarket stereo and i cant get any of the rear speakers to get sound whats wired wrong?

 

open the fuse panel on the side of the dash on driver side should have a list of what fuses are in what numbered spot. for the keyfob is it cold where you live and you had washed the carr that night before. now with the aftermarket stereo. on the pigtails you have for the factory harness of the car you have to make sure that the remote amplifier wire is connected. audis have a factory amp for the speakers and if you dont have them hooked up then you will only have just the front speakers. let me know if that helps. otherwise im lost to what is wrong.
