S4 Wiper motor access ?

My wipers don’t work and I’m not willing to risk removing the dash to repair as I’ve never needed to use them (until yesterday!). Is there any way to get to the motor to check the connections or where old dried up grease might be cruding things up? Where does the ground wire from the motor terminate? Other suggestions of things to try? Thanks. Dan S4 SE

You do not need to remove the dash just the glove box. And then you can split at the first wheel box . Try giving the plug on the base of the motor a wiggle.
