[s-cars] Low beams not working - update

[weski at verizon.net]

Thanks Tom.

I was thinking the same thing overnight - how could a ground on the 
passenger side headlight cause an issue with the driver's side headlight 
and visa versa.

Anyway - I had already replaced the headlight switch on the steering 
column two years ago when my high beams would turn on but not turn off 
unless I turned the lights off and back on.  Since then everything has 
worked great until recently.

I did buy some new bulbs and that didn't make any difference on the 
passenger side but it did correct the drivers side so now my only issue 
is with the passenger side low beam.  Ground into the headlight is known 
good as evidence by the high and fog working.  I'll take a look at the 
ground lead for the low beam - maybe it has become loose.  Unfortunately 
I have to do this with the headlight installed on first attempt as one 
of the lower headlight mounting screws is rusted tight so if I can't 
figure it out with the headlight in place this will turn into a bigger 
project as I'll have to pull the front bumper off to get better access 
to the seized screw - not a difficult job but certainly more work then 
it should take to remove the headlight.

It's progress.
