When the lights are on, the left signal light is on. The right one will work, but not the left. When the lights are off the left signal light will work but the lights on the radio will blink. When the lights are on, the emergency lights will dimly light and not flash. When the lights are off, the emer flashers will work but the radio light will blink.
"When the lights are on, the left signal light is on"
Do you mean the indicator light on the dash? If so, you have a bad ground wire on the left side. Turn on the four-way flashers, then walk around and look for the light that isn't flashing properly. Usually that will be in the front. You can also turn on the left turn signal with the head lights off, then if it's the left front that is the culprit, it will stop working if you remove the right signal bulb. Same on the rear. If the left one flashes off when the other three flash on, remove the right bulb and the left one will stay off.
