Hello my DRL on my driver side front stays on for a few months. Then I go over a speed bump or something and it stays off for a few months.

I suspect it being a loose connection but now it won't seem to come back on. What can I do to fix this issue? Thanks.

 

The first thing you need to do is find the loose connection. Then you should be able to fix it with a minimal amount of work.

 

Really hard to say, without seeing what's in place. Might be a relay that was starting to fail, and now it's dead? I'd start there, and if that's OK, trace all the wires and check every connection. Might even be a bulb, and if that's easiest to get to, switch that out and see what happens.
