Front Turn Signals do not work ONLY at night.
My front turn signals work fine during the day, but as soon as it is night they do not work and the back ones blink rapidly. 2008 Uplander.
Sounds like a bad turn signal bulb. You may have to take bulbs out one at a time and check with an ohm meter. You could replace one at a time and check after each one to see if that fixed them if you don't have a meter.
