this is not a really big problem because it has only happened a few times..but...sometimes if I start the car (A6 1998) the air will not come on and then i begin to drive and realize my blinkers do not work or my lights (if i have them turned on). so what i do is just stop and restart the car and wait for the a/c to kick in...i guess that is the only way to solve it? If i turn the car on normal and just wait for the a/c to turn on then it works fine..just wondering if anyone knows anything more about this problem.
