2001 Audi TT - Fans not coming on
 

Anyone,

Neither one of my fans are coming on. The aux fan isn't even coming on when I turn on the A/C(which is blowing hot air). After trying to find info online I decided to go ahead and change the thermostat. That didn't help. I have decided to try changing the switch located on the radiator next to the primary fan. And of course, I can only find it at the dealership. Am I on the right track? Can anyone send me an engine schematic/diagram?

By the way, I decided to go ahead and clean the throttle body because it was idling rough. Took me 15mins or so and worked like a charm! They were charging me $400 at the dealership!

Thanks,
