windshield wiper linkage diagram

The wiper linkage on the A4 model VW's are prone to seizing. Its a very common problem that can be repaired with a few tools. The cost of a replacement assembly has come down considerably, so my recomendation is to simply buy a new one and change it, but you can also follow these instructions and fix your old one if you prefer. Or, if its an emergency and the new linkage has to be ordered in and you need the wipers to work for a few days.
Firstly, you need a few basic tools:
- 13mm socket or wrench to remove the wiper arms
- 10mm socket or wrench to remove the assembly.
- large flat head screwdriver or prybar for prying purposes
- Wiper removal tool to take off the arms (I bought mine for $8)
- Small jaw puller to press out the wiper shaft
- Adjustable wrench to work the shaft back & forth if you don't have a puller
- Penetrating fluid & grease
- Round file to clean the hole.
