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

My 83 honda shadow has head light tail light and front markers but turn signals dont flash no brake light fan or horn or back markers what can i be they worked 2 weeks ago when i rode it last


It almost has to be a fuse or broken wire to the fuse. Check power to the flasher.
There are places on line to get free Honda Shadow manuals. I have a '96 Shadow.
Hope this helps.

Hope this helps.

The only thing that both the brake lights and tail lights use is a ground connection. Keep in mind the warning light on the dash may be for any exterior lamp. You may need to check the sockets and grounds on all four corners of the car.

1993 Honda accord EX no brake lights


This sounds like Brake Light Switch, can be found at any local parts store, for under $15 and easy enough to replace. The switch is located under the brake pedal and depresses when you hit the brakes, causing the brake lights to turn on. Replacing this is cheap and easy.

2006 chevy silverado 1500 front brakes are squeeking


on disc brakes there is a metal marker on them that when the pads get low on material it will make a squeeling noise to let you know its time to change the pads.. so I would say you are in need of front pads also even though they look good you are getting low.. this marker is designed to let you know its time before you get to metal to metal .. jerry

No headlights when turned on


Just a thought. I have a 98 626 5 speed. When the hand brake is applied the head lights go out but the marker lights stay on. Might be a switch issue with the hand brake...worth a look. The sensor should be located at the pivot point for the brake handle.
