Driving light not working
My passenger side driving light quit working and the turn signal. I have the fast flash going on but I checked the sockets and replaced the bulbs. When I turn the headlights on it works and the rear turnsignal works but it does the fast flash I also did a search on here but didn't see anything what do I need to check other than grounds since it.does.come on with the.head lights thanks in advance.

The daytime running light (DRL) is a dual filament bulb shared with the turn signal. The fast flash is telling you the bulb is bad so, from what you say, its the DRL filament thats bad. The DRL only works with the E brake off. Try another new bulb.
