[W126 Coupe] Passenger headlight bulb only glowing at half strength and it is not the bulb

[Dick Spellman]

Hi Cal,

When the mechanic started on your driver door work, did he need to go in 
behind the instrument cluster to navigate the harness that flows to the 
door column?  If so, the headlamp harness and a significant ground block 
reside behind there.  Could have tugged on a wire or two possibly?  
Otherwise, check your ground post on the front chassis adjoining the 
headlamp to the driver's side.  Should be right next to the 
receiver/dryer.  As Mike Ramay suggested... check and update the fuses 
if they have oxidized or are the originals that are known to heat up and 
let go on the tips.  You could check for current drain on the battery 
with the car off, all systems off to see if there is an active short 
too.  That would at least let you know on a system wide level of 
something is shorted.

Just a thought or 2.
