Question about 2003 Chevrolet Impala
I've had major issues since someone switched my multi function switch. They spliced the wires cuz they didn't know it plugged in. Since then the hazard switch has burned wires, it blows the fuse everytime you turn on a blinker, so no blinkers, brake lights, no A/C except on high fan & it's not cooling. Also the info center lights in dash are acting crazy...coming on & off over & over. Please help me...it has been this way for about 6 months & nobody has been able to fix it. I'm about ready to let it roll off a cliff & die.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

SOURCE: dash borad lights out
Were the fuses blown. If not it's the probably the bulb. If the fuses were blown check now to see if the new ones have blown again. If they have then their is a short in the wire. Let me know how far you have gone with the repair so I can direct you further.

TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

The problem is caused by the emergency flasher unit. This is a common problem and you can find a few youtube demos on replacing it. I did it in about 30 mins. I don't remember the cost but it was stocked at my local chevy dealership.

Yes, the brake light signal on American cars is routed through the turn signal switch. A new switch should restore both your turns and your brake lights.
American cars use the same bulb filament and same wire to the rears for both brakes and turns. Press the brakes when turning and both rear brakes will light, but since one side travels through the flasher relay, that side will blink, while the other side has a steady light.
