No power to headlights at fuses
 

Howdy!

Have a 94 E420 that had a bare wire shorting out a couple of pins in the fuse block. Here are the symptoms of wire on/off:

Wire on:
1. Headlights come on when car is started, dash switch turns on parking lights
2. High beams don't come on
3. High beams will 'flash'
4. High beams stay on if I hold the lever back in the flash position

Wire off:
1. Headlights don't come on at all (parking lights do) with dash switch
2. Headlights high beam works in flash position

I used a multitester and I show voltage coming across 'fuse d', which I don't see a listing for in my 'fuse designation' sheet, nothing on fuse 13 or 14 with the headlight switch to on.

I searched and found references to remote starters causing a problem and also upgrades to headlights. There is no remote start to this car, at least no fobs came with it, but the headlights/parking lights look different than on the 95 E320 I had. The parking lights are clear; euro upgrade gone bad?

I thought it might be the stalk switch, but since the high-beams flash and the low beams don't work, it would not be the problem.

Please let me know what to look for; perhaps someone has a picture of a stock headlight installation and the wiring connectors with wire color coding?

Thanks a bunch.

Power flow for headlights goes this way.....from H/L inght switch to combo switch & then to the fuses.

Guess you have either a bad combo switch OR h/l switch.

My bet would be the combo switch.

Turn signals are now intermittent so I'd say that's for sure it.

Saw a thread on fixing this, goes something like:

1. Disconnect battery
2. Remove driver side bottom panel from dash
3. Disconnect the combo switch
4. Plug in new combo switch
5. Reconnect battery
6. Test, if works then...
7. Disconnect battery
8. Remove steering wheel
9. Remove old combo switch
10. Install new combo switch
11. Reinstall the rest
12. Reconnect battery

Going to look up thread and print out now. Thanks!
