Replacing your dash board switches is easy as long as you do not try and pry them out from the front of the dash panel, doing this will only lead to damaging the wood on the panel. Removing the face plate that surrounds the climate control unit is probably more difficult than actually replacing all of the switches in the dash, but if you use care and follow these procedures you can easily replace them without causing any damage to the wood surround. You should replace the bulbs while you're in there. The bulbs are cheap and new ones will be brighter than the old bulbs

Over the years your car may have been serviced by multiple people including previous owners and this can lead to parts replaced with different size fasteners and hardware. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches. If something is different on your vehicle please let us know and share your info to help other users. If you have any questions or comments or even a different procedure you would like to share please leave it below and please leave your vehicle information.

Removing the cover plate on your W123 might be the most difficult part of replacing the switches.
Figure 1

Removing the cover plate on your W123 might be the most difficult part of replacing the switches. The wood trim actually has a metal backing (red arrow) on it that holds it to the face shield in front of the climate control unit. Most people try to use their trim removal tool and pry between the metal plate and wood thinking this is how you get the trim panel off but all you will do is separate the wood from the backing and damage both. As you can see in this picture a previous owner of this project car must have damaged the wood enough that they removed it and just installed the metal backing plate.

There are two cut out areas behind the metal plate that are designed to take the trim removal tool and ensure you get both the wood and metal coming off together (red arrows).

Get in behind the plate and gently pry it forward until it releases from the climate control plate.

With the plate off you can see the four small openings that the tabs on the plate sit in (yellow arrows).

Use a Philips head screwdriver and remove the five screws holding the cover plate in place (yellow arrows).

You can now remove the unit out from the center console.
Figure 7

You can now remove the unit out from the center console. You do not need to disconnect the unit just pull it forward so you can reach your hand in behind the switches

The switches can now be easily be pushed out from the rear of the panel.
Figure 8

The switches can now be easily be pushed out from the rear of the panel. Apply pressure to either the top or bottom of the switch and they will push out from the panel.

Simply unplug the old switch (yellow arrow) and plug in the new one.
Figure 9

Simply unplug the old switch (yellow arrow) and plug in the new one. On some switches there will be one or two small cables going into the switch, this is the optical cable that provides light to the switches (red arrows). Simply unplug the cable by pulling it back and plug it into the new switch, but do not fold or crick the cable or you can break the flow of light. This is a really good time to also replace all of the bulbs on the climate control unit and optical cable so please see our article on those procedures. Installation is the reverse of removal.
