2003 Honda CR-V EX headlight problem...help!

Headlight problem started about month ago with passenger side
out...closing hood would cause it to come on at first.

Replaced both headlight bulbs and passenger bulb filament was
bad...both headlights now worked.

About a week ago the drivers side went out...ck'd filament good
and swapped out bulb......no go..worked on this for hours
cleaning connectors wiring prongs in plug....no go.....

Plugged bulb in while out of socket touched ground no go....but,
after pulling on wires and plug bulb came on.

Replaced bulb in assy replaced rubber plugged in and again its
does not work.

My guesses or a broken wire bad connector somewhere...ground
etc..

Does anyone know the schematic on this vehicle where the plugs
and connectors are?

Its hard for me to believe a almost new car has a broken wire
or corrosion like you find on 20-30 year cars.

Any input on T/S or anyone had this problem?

Thanks for any help!
