I have high beams, but no lows. I put a meter to the bulb plug, and got voltage on high setting but nothing on low. So Im thinking either switch or relay. Anybody else ever have this problem, input would be appreciated. Thanks.
 
I'm not positive but some bulbs like HIDs have only 1 setting. Or so I have read somewhere on the forums.

Did you check you headlight fuses? I think theres one for high and one for low?

I was thinking the same thing, I've spent so much time looking at the fuse box but now I'm almost blank. I think there is but I can't remember.
 
Well it would only make sence to have one for each. I guess I could always go out to the garage and look for you lol.
 
It's pretty simple, your bulbs are burnt out. Replace both of them and you should be good.

There are actually 2 filaments in your bulb, one for low and one for high. Your lows obviously get used more. Also, if you car comes with daytime running lights, the lows are always on. They only run a lower voltage.

So go change your bulbs, simple enough?
 
^^^ what he said - take the bulbs out and look at the filaments. its not uncommon for the lows to blow out, and not the highs

That statement negates the above.<that statement="" negates="" the="" above.=""></that>
 
Had the same problem 2 days ago, both lights worked only on hi-beam. It was the bulbs. I changed them and all is OK now
 
He said he had no voltage on the low beams part of the headlight plug, but then again who knows, try a new bulb first.
 
Thread cleaned up. Keep your arguing to yourselves, please.

To the problem at hand -- is it possible that the car is smart enough to 'turn off' the voltage to the lows if it knows the bulbs are burnt out? I know little about light wiring, so that's about as intelligently as I can phrase it, LOL.

Either way, buying a new set of bulbs couldn't hurt, cause you'll wind up using them at some point. Even if they don't fix the problem, it's not like the bulbs aren't gonna burn out sooner or later and need replacing.

There is nothing smart about this car :(
 
lol i think she means that something had to cause the fuse to pop (if thats also the problem)...and it was probably the bulb going out...

Thats pretty much what fuses do.


Anyways, just go to wal-mart and get a some new ones.

^^^^^lmao, Its not the fuses since both beams share the same fuse. It may be the bulbs, but that doesnt explain the lack of voltage, maybe the the cuircit could be cut. I have heard of simular featers on some cars. Thanks for the info, I will try bulbs as soon as I get back from Miamy on tues, and update on the results. I really apriciate loaning me your brains lol. You guys are always helpful.
