My drivers side low beam light will turn off shortly after I turn the lights on. It will turn back on if I go over a bump hard enough, as though something is loose and not connecting right. I double checked the connections and can't figure it out. What is usually wrong when a light intermittently keeps going out? Even after replacing the bulb and cleaning the connections?

 

bumppp

 

mine...did the same thing... finally i replaced the wiring and got a new light housing and all is fine.

now my passenger one is acting up...one minute it works....another it doesn't....

 

i had an issue with that a couple yrs back, replaced the one bad light that i had and still had the problem after a couple days of TSing on my own finally gave up and tookit to GM. Ended up being a relay somewhere under the dash think is was about 150 to have them fix it

 

Check the harness they tend to develop some corrosion

 

Wait!!!! ,... Are you refering to the $6 flasher under the dash?!
