i brought my 97 a6 to the local oil n go to get the ac recharged. they did that and checked for leaks, but they found out that the ac clutch wont engage when the switch is turned on. according to them its not the actual clutch its electrical. does anyone know how i could figure out whats could be wrong with the electrical system? (btw the switch im talking about is passenger side underneath the hood. the place i took the car is right next to an audi dealership and the guy there didnt know what could be wrong)
