Anyone have this issue, my auto lights come on, then after a while they may go off. And I have to turn them on with the manual switch. The switch is good, and have replaced the light sensor.

 

Did you try adjusting the sensor using the plastic screw on its side? Is the replacement sensor used or new? It may just need an adjustment. Also make sure the sensor is plugged in ALL the way in. I had a similar issue and come to find out the sensor needed to be pushed in a little more into the plug.

 

I've had two both used. I'll have to brake down and buy new. If that doesnt work. I have addjusted them

 

Before you do that make sure your fuse/relay(s) are ok as well. Check your owner's manual for location (sorry i dont have mine). I don't know your yr/model but i believe it may be more than one if you have daytime running lamps. If you don't have your manual, maybe someone here can post where you could find them if you tell us whether or not you have DRLs.
