It seems to be obvious that something is wrong with that side of the vehicle so you must be doing something wrong.

You might see voltage difference in the socket, but it may not offer enough current to light the bulb. To find out, you put it back together, and try to back-probe into the connector where the wires feed in with the light 'energized' and the bulb in the socket. That would show a voltage drop if the current were not available. I think.
Check your power distribution panel for a relay that powers the headlights. I know the high beam is relay operated as I can sense the delay after switching to or from high beam. If there is a relay, it could be bad. Swap from L to R and vice-versa to see if the problem tracks the relay.

Good point! Might be a problem that this tool might help: TESlite Voltmeter Leads, I have one but never ran into a situation where I needed it. Even a simple 12V test light on the connector power contact comparing to the good side might help.

Ok I back probed it and had power until I plug the bulb back in ,then the power drops . would there be a separate relay for drivers side and passenger ?

With the bulb in, lights ON, is there anyway you can pierce the wire away from the connector? Some meter probes are sharp enough but hold a piece of wood behind the wire to protect your fingers in case it slips off!
You could have a corrode junction point feeding power to that side so when you put a load on it, voltage drops.
EDIT:
Just looked at my '09 Electrical Diagram Manual and low beams are solid state logic controlled with a separate FET for each side. What year is it? It show a separate high beam relay(non-serviceable) all inside the SJB. Have you tried the high beam on that side?

I looked at the shop manual wiring diagram for the '06 escape/ mariner. The escape has some 'stuff' in or near the headlight that I don't quite get. Looks as if there is a motor in both headlights, but I haven't a clue what it does.
That said, the power for each side is a separate output from the SJB, one for hi beam and one for low beam, for each bulb. The power comes from the SJB {Smart Junction Box}, and it may have relays internal or external. The switch on the column provides a ground to the appropriate pins on the SJB. Given that, it makes sense that a relay is energized by a ground completing a path, but in the diagram it is labeled "logic".

I am pretty sure that PWM is used for the DRL system, or they are feeding AC of reduced voltage.
The symbol I saw on the diagram was the standard thing for a small DC motor. A circle in the middle with two squares on opposite sides. It also looked as if the motor moved an assembly in steps.
I saw a mention of 'active lighting' or words to that effect, but since I don't own one, I will spend my time reading of other stuff and answering questions with more questions...

My manual shows that a motor has a "M" inside the circle for a motor along with the squares, two squares is a single speed motor and three is a two speed.
The 2006 PC/ED manual was the last to included memory locations for PIDs which can be used to program a ScanGuage II, if you know how which isn't me!

May be the symbol for a stepper motor lacks the "M" and adds a 'sawtooth with pointer'.
Either way, the SJB supplies the power. I may start buying older vehicles. If the SJB retails for what I expect, and is 'unrepairable - no user serviceable components inside', and it fails like this, i.e., one headlight out, I'll go back to the old pull switch or rocker.
I am smarter than a Smart Junction Box. Fifth Grader? Maybe not.
