Blown Dash light
Does anyone know how to change the dash lights in an 82' 300d? Can i just pry the plexiglas cover off or is there a special tool?
Any help would be greatly appreciated. Thanks, Andrew |

Dont pull the plexiglass. You have to push the entire instrument panel from behind. If you get lucky, you can changeout the bulbs without removing the wires behind the instrument cluster.

You can also pull the cluster out using a two pieces of a coat hander with a bend in the end of each one about a 1/4" long. Once it's out you disconnect everything and can pull the entire cluster out. You may have to do this depending on which bulb is out. If it's one of the bulbs on the lower part you can probably reach them from underneath like stated previously, if it's on the the bulb on the top you'll probably have to pull the cluster.

Yes you remove the whole instrument cluster.
1st. remove the drivers side lower knee bolster panel. 2nd. Open the engine compartment and where the speedometer cable goes to the tranny, you will see it attached to a bracket. Disconnect the speedometer cable form the bracket and push the cable into the firewall to allow the instrument cluster to move out of the dash. 3rd. From below the dash push on the back of the instrument cluster to dislodge it from the dash. When it comes out it will not come out all the way. The items that prevent this are the wire harness, the speedometer cable and the oil pressure gauge line. Pull off the wire harness Unscrew the speedometer cable, it may require pliers, but be careful not to cross thread it going back on. Use a wrench to disconnect the oil pressure line. Now the instrument cluster (IC) will separate form the dash. The IC lights are a brown base light socket located at the top of the back of the IC. From the IC light prisms at the top of the inside of the IC move straight back. The brown base units are the bases of the lights. unscrew them and replace the bulbs. You may be able to replace the bulbs while the IC is still attached via the wire harness oil line and speedometer cable. It will allow your hand to just fit between the dash the IC. IF you know which brown bases are the lights you can do it this way. Dave

I guess I'm not surprised that pulling the W123 cluster is just like the W124...
http://www.peachparts.com/Wikka/W124InstCluster Maybe that DIY should be called W123/4/6 so more people will find it.

Are you positive it's the bulbs? If dash is completely dark, it could be the Pot. (dimmer switch) on the cluster.Go out at night....the darked the better, turn lights on and flip dimmer make and forth rapidly a couple of times. Then turn dimmer slowly from one side to the other, looking for any signs of light.

When you take the oil line off USE 2 WRENCHES! Most people don't and over time can weaken the fitting causing an oil leak.

Just curious, how does using one wrench cause a weakening of the fitting?

It's also much easier, especially if you can position the two wrenches like a "V" and squeeze them together -- this works both for loosening and tightening. |
