[TR] a bulb not doing anything, not TR

Re a 2003 Dodge Caravan, not a Triumph.

Our 2003 Caravan has a non-functional right front parking light.  It is not the bulb; I checked it, even swapped it with the left front bulb.  It is not a fuse; they all appear good, and the right rear is working.  (The fuse markings are ambiguous but appear to say that both RF and RR bulbs are wired together.)  It does not appear to be a relay; I re-seated them all anyway.  The turn signals work just fine.

I put a voltmeter on the wires, saw no voltage, but may have been thwarted by the difficulty of getting a good ground through paint or surface corrosion everywhere.  I disconnected, checked the voltage on, and re-seated the plug going to the bulb holder; still saw nothing.

The most likely cause would appear to be a corroded connector somewhere out of sight in the line going to that bulb only.

Can any of you suggest which part of the dashboard I should disassemble to find it?  The car was inspected in August, so that hurdle won't come around again for a while.  But on the other hand, it is still a non-functional bulb that I would like to fix and may be required legally to fix, inspection or no.

In the meantime, the weather is getting cold.
