I need help with the follow repairs to my 04 A4:

1) Windshield Wipers
My passenger-side wiper-arm is broken (yes the actual arm). The little latch that clips onto the wiper-blade is broken. Is this a easy DIY job? If so where can I get the proper parts?

2) Speaker Cover
The speaker cover on the driver-side door has a dent in it, know where I can get a replacement cover?

3) Tail-Light
The passenger-side tail-light is burned out (well I think only one bulb is). It's still lights up, but is now significantly not as bright as the driver side (so i'm assuming there are two bulbs in there). Can I just get any replacement bulb or is it specific?

Any help with these would be much appreciated!

Cheers.

 

the tail light: open the trunk and on the side under the carpet( little round tab) theres one screw take it out and the assembly slides out , take out the bulb thats burned out and get an identical one any autoparts store
wipers: go to the dealer they'll help you with the parts the job is pretty much self explanatory.
speaker cover you can get at the dealer or a scrap yard
