High beams but no low beams on aveo - Aveo Chevrolet Cars & Trucks

Bright lights wont shut off ? Assume you mean high beams ? Reading how they work might thing high beam relay has stuck contacts inside .

Headlamps
The headlamps may be turned ON 2 different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the AUTO position, for automatic lamp control (ALC). During ALC, the headlamps will be OFF in daylight conditions, or low beam operation in low light conditions. Battery positive voltage is supplied to the low beam relay and the high beam relay in the underhood fuse block. When low beam headlamps are requested, the body control module (BCM) supplies ground to the coil side of the low beam relay. This activates the relay and the relay supplies voltage to the left hand low beam headlamp through the LH LOW BEAM fuse and to the right hand low beam headlamp through the RH LOW BEAM fuse. Ground for the left hand low beam headlamp is provided at G101. Ground for the right hand low beam headlamp is provided at G102. When high beam headlamps are requested, the body control module (BCM) supplies ground to the coil side of the high beam relay. This activates the relay and the relay supplies voltage to the left hand high beam headlamp through the LH HIGH BEAM fuse and to the right hand high beam headlamp through the RH HIGH BEAM fuse. Ground for the left hand high beam headlamp is provided at G101. Ground for the right hand high beam headlamp is provided at G102.

On the inside of the lid is a diagram .

It could be driving lights mode instead of low beam. Check connections.

I would check for the groundwire continuity

The high beam continues to work on both sides...I pulled the Driverside headlamp fuse and then both left and right beams lit up but very dim.

You have to replace the headlight bulbs. There are two elements in each bulb one for low beam and both for high beam. The low beam burns out first...

That should be the problem.
Check the voltage at the dimmer on each setting.

Both highs and lows coming on when flipping to highs is normal. (You low beams are dual filament) Now low beam issue is either "lo beam fuse" in your fuse box or dimmer switch (switch used to flip between high/low beams. Check your fuses first, it their good then you need a new dimmer switch.

Hi.
1. The buld holder has gone bad.
or
2. The wiring to low beam needs to be looked into.

DID YOU CHECK THE BULBS?

probably the connections on the lever/arm .
