hi,
I have 2002 A4 1.8T Q.
I set up the dome light to turn off after start the engine, but last night it didn't turn off. I also found that all of window control, side mirror control, and door lock is not working! It seems like it has electrical problem with the driver side door. please help me.
Thank you

 

Did you check any fuses yet?

 

no, where can I find it and how to check?

 

On the driver side panel, below and to the left of the steering wheel, there is a slot for you to stick a screwdriver and pop that panel off. Inside the panel is a schematic of each fuse and what it controls.....

 

Thank you Agent1.8.
I will try that.

 

I just checked fuses and and they seems ok. I replaced the fuse for double check, but it still not working. Are there any other options?

 

make sure u looked at the right fuses , and then check the master fuses in the fuse box under the hood

 

I would take Borninrussia3's advice, it would strike me odd that it wouldn't be a fuse or a master fuse...
