92 cadillac brougham instrument cluster and climate control flickering on and off when left turn signal is on and when brake pedal is pressed goes away when headlights are turned on but when the left blinker is turned on the turn signal doesn't blink when the headlights are on what could be the problem?
It could be the turn signal switch. I have a '94 Brougham limousine and had issues with the brake lights, interior lights, and dash lights flickering and staying on. I traced it back to the turn signal switch. Check the wiring at the bottom of the steering column. Look for worn insulation, and/or poor connections. HTH. -Jim
