The dim headlights on my 2005 impala stopped working (both dim lights). The brights work and all other lights work. Ck'd ground(good), ck'd both bulbs with ohm meter(good), reseated connections. Any ideas

Ck the bulbs, ck for power & ground at the sockets w/ headlights on, Poss headlight switch, relay & fuses with a test light.

check the bulb sockets , ck your ground

First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!

i wood just for kikes ck foses . but doge had bad light awitches

ck for power to bulbs ck fuses ck switch

bad ground with the dim headlight ck the headlight ground in that area

If you have dim headlights most likely cause is a bad ground. ck the black wire at the headlight bulb with test light connected to battery pos +12 v if test light does not light or is dim than you have a bad ground wire that needs to be repaired

ck if you need a tune up, lights work off the battery,charge battery ck electric coil

ck fuses. ck both bulbs. I know its crazy but I have had both bulbs low beam out. if the bulbs are good then the combination switch may be bad.

Ck the ground wire for this light.
