Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.
Hey how are you
you are very welcome
1- is there power on the blower motor connector if testing with a test light switch on & blower switch on
2- all fuse been checked ?
3- if the fuses are good & blower motor and resistor new .
there is nothing left but the ac controller or the ground supply to it from the ECU .
usually we see bad ecu on a higher mileage then your car , so most likely the ac module is this issue ,but testing is needed .
Please let me know

1-vw has so many variation of fuses boxes and fuses panel label, you will sped hours trying to find it .
with a test light go across all fuses in both boxes see if any bad and replace .
2- you should get 12 volts on the blower motor and a ground ?
CHECK ALL FUSES ,DID YOU CHECK ALL FUSES ?
ok sounds good let me know
Tell me what engine you have please
I believe the AC control module will be the issue .
now i don't know about these other lights .si voltage and charging system good in the car .
low voltage will cause all kind of problem ,if you confirm the battery,alternator & fuses are good ,then replace AC module
if that works for or you need more assistance on it
I also need production date, look at the sticker on the door frame it will sayt the production date , like 2/3/06 example ?
yes it can be,
but let send you the circuit diagrams to check few things be right back
