Low beams not working but high beams are on a 2000 chevy metro

You can't use High Beams as dipped, the spread is different. Just go to another garage, it can only be the bulbs, the connection, the fuses or the relay. In fact you can check all those yourself! It appears to be a known issue on the Impala. Look at the videos

I have seen both low beam bulbs burn out at the same time.
Its possible the relays have burnt out for the low beams.

Check bulbs. had this happen on my intrigue had no high beams but lows worked. If bulbs are fine check fuses and relays.

It can be faulty low beam lamp or its connection issue for low beam lamps.

sounds like the problem is the dimmer switch, get a price on the dimmer switch. If you have to, get one at a junk yard . It's cheaper.

most cars have 2 fuses 1 for low beam 1 for high beam look under the hood for a fuse box read the back of the lid to find out witch fuse

Check the fuses under the hood...chances are it's one of them....there's not much left to check after that....check the fuses inside the car as well...it might be the high beam switch is bad that switches the low beams to high beams inside the car.

do your flash to pass lamps light when you pull the stalk towards you? If yes, the bulbs are ok.
Do the hig beams work?
Your headlamps have sepaerate fuses for each headlamp and you have a low beam relay and a high beam relay under the hood in the black box.
If everything is out, I suspect a bad headlamp switch.
Check car-part.com and look on page with * for cheapest price.

Your owner manual will identify fuses & relays.

PS, You did not recently instal high current bulbs did you? If yes, put originals back in.

HEADLAMPS

The voltage is supplied to the lamp switch through a fuse. This fuse is located in the central junction box in the left-hand footwell.
When the headlamps are switched on, a voltage is supplied to the high beam/low beam switch and to the low beam relay. The relay for the low beam is located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "low beam", then a voltage is supplied through the low beam relay to the low beam part of the headlamp assembly. The left and right-hand low beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "high beam", then a voltage is supplied through the high beam relay to the high beam part of the headlamp assembly. The left and right-hand high beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
