electrical connections behind front bumper - DS

[millertyme]

Bernard,
I seem to recall that 2 of the wires were blue, and the third was red
and much heavier (likely the + volts supply).  
But, The fan works, so that shouldn't be an issue, but it may be causing
some extra drain due to corrosion.  I will check it out and likely clean
up the posts tonight.
The volts are being read from the climate control.  
I was just reading on the smj site about the battery cable splice and I
will check the reading directly at the battery tonight.
Thanks for the insite, and if there are anymore, please don't hesitate
to chime in
Thanks again
Brian

Sounds like you are looking at the radiator fan resistor -- they are 
usually a blue color if you rub the dirt off a bit.

Your low and medium radiator fan speed leads route through the 
resistor.  If your system is on A/C, the low speed should be on unless 
the system demands med or hi. (The fan is never off in A/C mode).  If 
the fan does not work in low or med, this is the area to look.

Where are you measuring the 12.5 V?
