If you need to get access to the heater controls or your stereo unit on your W201, you will need to remove the center console. While this is a relatively straight forward job, I would recommend you take lots of pictures of the wiring behind the console for reinstallation purposes. Mercedes-Benz made several changes to the interior on the different years and models of the 190-Series, but they are all similar enough that this article should get you through it.
Begin by pulling the knob on the fan control switch straight back and off.
Next, open the ashtray panel and remove the ashtray. With the ashtray out you will be able to see the two screws holding the ashtray assembly to the console. Using a Phillips-head screwdriver remove these two screws and the ashtray assembly from the console by disconnecting the wiring harness. With the ashtray assembly out you can now remove the two Phillips-head screws holding the bottom of the console to the tunnel mounting plate.
There are two Phillips-head screws under the climate control panel that you will need to remove. You will need to look up and under the bottom of the face plate to see these.
Next, using small needle-nose pliers, remove the center vents. If your vents are in good shape, place a rag around the pliers and pull the vents straight out. They are just held in by friction. With the vents out, remove the two Phillips-head screws at each end of the center vent plate.
You can now pull the center console up and out from the center tunnel.
Carefully turn it sideways and remove the wires connecting to the radio and climate controls.
Installation is the reverse of removal.
Begin by removing the knob on the fan switch, it just pulls straight off.
Next, remove the center vents. If your vents are in good shape wrap a small cloth around some needle-nose pliers and pull them straight out. If your vents are in the same shape as the ones on our project car, using a cloth will not make any difference.
