Default 2003 TT A/C controls and A/C not working

Picked up this Coupe about 6 months ago and has been a great car.

2 weeks ago the AC quit working, checked the fuses and they are good. The system is full of Freon… The car has not overheated sitting in traffic and you can hear the fans come on then the car gets up to temperature.

A friend tried to bypass the pressure switch, when he did this it killed my AC controls. Now the blower fan or display does not work.

Where are the relays or control modules for this car? I found the fuse box in the dash on the driver’s side but cannot find relays. I’m going to look at the fuses on top of the Battery when I get home this evening…

I found a blown fuse for the controls so I have that working now.

I checked the compressor and its not getting any power. The fans are running on the car and when it gets hot the high speed fans will come on.
