Question about 2007 Chevrolet Uplander LT Minivan
When my head lamps are on my front signals wont flash what is the problem
About the only thing that the headlights and turn signals use together is the ground circuit. They get power from two different circuits.
Could be a ground problem in the harness or one of the connectors.

Well it sounds like you have a short circuit somewhere. it apperars to be messing with the relay that you replaced. have you checked all the fuses in your fuse-box? how about all the bulbs on the exterior of the vehicle? try those things then post back.

Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

First thing i would do is chg. the break light switch, and make sure to chk. all grounds around tailights, sometimes if there is a ground problem it will travel back thru the hot wire to get a ground, witch in turn makes everything go wackey.

if you're getting a more rapid flash in the front you have a possible blown relay to the back. Check fuses first and see if those are out.

the flashing is genreally controlled by a relay switch in your car. probably the fuse for your relay is blown or your realy itsef might need to be replaed.

The Turn Signal Indicator
The Sidemarker Lamp
The Sideview Mirror (Pontiac Thunder only)
The turn signal switch also sends a separate on-off signal to the Daytime Running Lamps (DRL) control module, which relays the signal to the appropriate front turn signal. The front turn signals are grounded at G101 and G102. The rear turn signals are grounded at G401. The sidemarker lamps are grounded through the corresponding front parklamp.
The sideview mirror turn signals are a bank of LEDs placed behind the mirror glass.
The hazard lamps operate on battery voltage. The HAZARD fuse supplies battery voltage to the turn signal switch. When the hazard switch is pressed, the turn signal switch sends battery voltage to the hazard lamp/turn signal flasher, which sends an on-off signal to the turn signal switch. The turn signal switch send the on-off signal to all the turn signal lamps, causing all the lamps to flash including both IPC turn signal indicators. The hazard lamp/turn signal flasher is grounded at G200.
When the parklamps are ON, the sidemarker lamps receive voltage from the park lamp supply voltage circuit and illuminate. The sidemarker lamp is grounded through the corresponding rear turn signal. When the turn signal switch is place in the left or right hand position, the rear turn signal illuminates and the sidemarker lamp will loose its ground, causing the sidemarker lamp to turn off when the turn signals are on and to illuminate again when the turn signal is off.
Which blub an socket did you replace ? check the other blub ? The switch and or the flasher module can cause this problem .
Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column.
Did you complete the replacement?
