When starting my Sephia each morning, both the dash lights and headlights are dim - about 50% strength for up to 1 minute. Then they both come on at full strength. Could it be a loose, or bad wire or connection?
I think it may be due to the alternator voltage output being low and then picking up to where it should be. You can check the battery voltage to see if that is true.
Thanks. Advance Auto checked the battery & alternator this weekend & said both were fine. They checked it during the day when car was warm. Think I’ll have it looked at.
