2010 impala high beams do not come on, light on dash comes on, replaced bulbs still don't work, checked all fuses, look good


High Beam Headlamp Operation
Battery voltage is applied at all times to the coil and switch sides of the HIGH BEAM PCB Relay located in the underhood fuse block. When the headlamp dimmer switch is placed in the high beam position, the headlamp dimmer switch signal circuit to the BCM is pulled low signaling the headlamp high beam request. In response to this signal, the BCM applies ground through the high beam relay control circuit energizing the high beam relay. With the high beam relay energized, battery voltage is applied through the switch side of the relay, the left and right high beam fuses, and the high beam supply voltage circuits illuminating the high beam headlamps. At the same time the BCM sends a GMLAN serial data message to the instrument panel cluster (IPC) requesting the IPC to illuminate the high beam indicator. Ground for the left headlamp is provided at G101 and the right headlamp at G100.

I'm needing the wiring diagram for my 2007 Chevrolet Impala LT 3.5 tail lights.


Go to http://www.bbbind.com/free_tsb.html free wiring diagrams ! You having tail light problems ? Do you know how they work ?

They are turned on by the BCM !
Park, Tail, Marker and License Lamps
The park, tail, license, and marker lamps are turned ON when the headlamp switch is placed in either the HEAD or PARK lamp positions, or anytime the automatic light control (ALC) turns the headlamps ON. When the headlamp switch is placed in the park lamp or headlamp positions, ground from G202 is applied through the signal circuit to the BCM indicating the park lamp request. In response to this signal, the BCM applies ground through the park lamp relay control circuit energizing the PARK LP PCB Relay. With the relay energized, battery voltage is applied through the switch side of the relay, both park lamp fuses, and the supply voltage circuits illuminating the park, tail marker, and license lamps. Ground for the left front park and marker lamps is provided at G101 and the right front park and marker lamps at G100. Ground for all rear lamps is provided at G302.
Turn Signal Lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block supplies battery positive voltage to the body control module (BCM) for turn signal and hazard lamp operation. When the turn signal switch is place in either the LEFT or RIGHT position, ground from G202 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. The BCM also sends a message via GMLAN to the instrument panel cluster (IPC) to cycle the turn signal indicator ON and OFF depending on the position of the turn signal switch.
Ground for the turn signal lamps is supplied as follows:
?€¢
G101 provides ground for the left front turn signal lamp


?€¢
G100 provides ground for the right front turn signal lamp


?€¢
G302 provides ground for the left and right rear turn signal lamps

I have a 2007 Chevy HHR..the tail light don't work the bulbs workI have turn signals and brake lights..no owners manual in car. check fuses can't locate the fuse for tail light is there another place


Your talking about the rear park lamps, but, do the front park lamps work?
Note the picture.
Underhood fuse box, 68 is park lamp relay, 69 is park lamp fuse.

Where can i find a wiring diagram. For a horn on a 1995 Suzuki sidekick 2dr convertable


easy
if the relay output hits 12vcd to horn (green-blk)
then the horn is bad, a $10 walfart meter solves that riddle.
if 12vdc gets there and the ground at the horn is bad, it fails.
as all do on all suzuki's (using body grounds ,sux)
caused by rust there.a G101 point.
clean off rust under horn mount yet

this is it !

What would I look at if my lights are very dim on both sides when their on regular. But on bright, the left side doesnt work at all & the right is working on bright perfect? Would it be the...


If the lights are dim, you'll need to check the ground for the front lamps. The ground is G101 ( #3) and is located on the left front of the radiator support.
