I have a ford freestar with the driver side head lamp is dim..,Can anyone tell me if the lamp is going out or if its a electrical issue?

 

Usually,,,,,,,,,, when that happens, that light has a poor ground connection. One of the 3 wires from the bulb assy is a ground wire. The other 2 are for hi and lo beam. The ground wire may be connected to the fender or to other sheet metal. Trace it and check where it is bolted to the sheet metal.
There could be a poor connection right in the bulb socket also.

 

Hanky, Thanks so much for the information. I found the loose ground in the headlight socket.
