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

Thank You

I get a flash of power on the blower motor connector and then goes right back to zero. The manual is no help with fuses as well as looking up online. What fuses do I need to check?
Customer: replied 27 days ago.
How many volts should I be getting at the connector
Expert:  Chad Farhat replied 27 days ago.

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 ?

Customer: replied 27 days ago.
No power at blower motor I checked fuses that I found online and they check ok
Expert:  Chad Farhat replied 27 days ago.

CHECK ALL FUSES ,DID YOU CHECK ALL FUSES ?

Customer: replied 27 days ago.
Checked all the fuses under the hood now I will do all of the ones in the dash
Expert:  Chad Farhat replied 27 days ago.

ok sounds good let me know

Customer: replied 27 days ago.
All fuses check good but now I'm getting a couple warning lights for power steering and transmission. Check those fuses they are in the correct position and still check good. Blower motor is still not getting power
Expert:  Chad Farhat replied 27 days ago.

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

Thank You

Well the manual said the power steering light will go off once I've driven a while prob because I disconnected the fuse. What am I looking at here?
