Parking Brake contact switch 1997 C280 MBZ

Question by janiec posted 6 months ago in 1994-2000 (W202)

I had a mechanic tell me to replace the PARKING BRAKE CONTACT SWITCH, I bought one.

The mechanic is gone.... 

Can anyone tell me where it is located?  The Brake  indicator on my dash stays on and it beeps constantly when car is in motion. I've searched YouTube and Googled it.

Help!  please.
