Hi, having weird issues with directional/lights on car. To list the symptoms:
Both directionals work if headlights are OFF
Left directional sticks on if headlights are ON, right continues to work
Checked all headlight, brake and directional lights. The only one that was blown was the upper left front directional. Tested connection and no power going there, wires look good.
Using the brake causes the dash and radio lights to dim
Using the left directional with the headlights off causes the dash and radio lights to flash against the blinker.
Replaced the flasher switch, with no improvement.
The car does have automatic headlamps, if that helps.

Please help! Where do we look next!?
Thanks in advance,
Keith
