Yes, the dimmer switch could be At Fault but, be sure the bulbs are okay before you spend anymore money.
have you replaced the dimmer switch? if not that may be the problem. I had the same problem in reverse( brights worked but headlights didn't) water damaged the dimmer switch on the steering column once I replaced it all was good.
If your high beams still work it is the dimmer switch.
This Had happened to me... Try changing the dimmer switch... It cured my problem.
i had this problem. mine was a bad dimmer swith.
Your headlights may not dim because you don't have dimmer lights. Dimmer lights can blow and leave you with just the high beams.
could be bad wiring
The instruments light dim for night driving when the headlights are turned on. Check to insure that your dash dimmer switch is on high. If it is, then you have a problem with either the dimmer switch or the wiring.
Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem
The headlamp switch controls the power to the dimmer switch and then on to the headlights.The headlamp switch controls the power to the dimmer switch and then on to the headlights.
problem is in dimmer switch on floor
I would suspect the dimmer switch or "combination switch".
They might have forgoten to plug the dimmer switch back in. The dimmer is attached to the column. Find someone to look under the dash, or take it back to whoever replaced the column. It would be their responsibility to make sure everything is right.
