the carbaretta could have blown mate
If parking and tailights are working could be headlight switch--rheostat for dimming control could be bad
Answerthink maybe you need to get the light switch testedReplace the Turn Signal Switch then all will be fine.
When the signal lights are not working on a car, there are a couple of things that could be going on. One could be that the bulb needs to be replaced. The other possibility is that the signal relay needs to be replaced.
The dim lights on a 1994 Grand Prix could go out when the headlamp switch is on if there is a short in the wiring for the headlights. There could also be a problem with the bulbs themselves if they were touched during installation. The oils in the fingers can short out new headlights.
Blown fuse or the lights are just blown and need replacing.
If the headlights are not working correctly on a 1990 Corvette, the fuses or lights could be going out. Replace the old fuses and check that all wires connected to the lights are functioning correctly.
First check your fuses if none are blown then check the switch.
If the headlights on the 2004 GMC Envoy are not working, there could be a loose connection somewhere. If all of the other lights are working, it is most likely not a fuse that has blown. Double check the wiring to see if there is a loose connection.
How bout the turn signal indicator switch located in the steering column.
The headlights could have bad bulbs or a bad fuse; the two sets of lights are on different circuits.
Parking and dash lights also on this circuit - do they work? Check fuses Could also be a bad headlight switch
If the turn signal is working it's either the brake light switch or the turn signal switch.
