My left turn-signal dash light (arrow) has decided to stay on even when not using that blinker. It flashes correctly when I do use that blinker, and the tail lights blink properly as well. Even though the dash light stays on, the tail lights on that side do not stay in the brighter "on" position. Where should I look first to try and figure out why this is staying on? Thank you in advance for your input.

sound to me like you have a bad ground , check all your grounds under the dash... ect.. good luck , chris :thumbsup:

Does the dash T/S indicator only glow with the parking/headlights on? Like Chris said, check for a bad ground. But, the ground problem is probably at the left parking light. The dash T/S indicators are tied into the parking lights. When there is no ground at the parking light socket, current flows from the light switch, through the parking light filament, through the T/S filament, then through the dash T/S indicator to the ground on the dash.

Yup, like larry said, check the grounds at the tail light on that side, also the parking light in front.

Now that you guys mention it, I noticed the other night while the car was idling in the driveway that the front parking light on that side was out. I tapped on the glass and it came on. Since then I've been meaning to look at it. Sounds like this issue is connected (literally) to the T/S light.
