2003 GMC Yukon

Blinker problems. Car is in park signals work fine when in gear the right turnsignal is engaged and the brakes are applied the brake lights all light up and signals go blank, also the compass in the mirror is either totally blank or flashing moe worried about the signals

  1. Since they work fine in park, do they also work fine in park with the brake on? If yes, then since it only has an issue when put in gear I would lean toward a back feed issue coming from the gear selector switch(neutral switch). Or possible loose or corroded ground connections.
