I have done a lot of "googling"
Just bought a 2008 tahoe hybrid and the dealer gave me a laundry list of repairs. I thought replacing daytime running lights would be easy... after a little bit of fun I did manage to get the new lights into the sockets. When I tested they would not come on, keep in mind I’m not sure what brings then on.

So I started troubleshooting ...
tested system with key on and in drive
-power on fuse 31 but no power on 31
-Fuse 31 and 33 not blown
-Bulb base has good connections with no melted or burnt spots
-Parking brake is off

My question(s)
Is there a setting I have overlooked ?
Am I testing it currently?
Is there a common issue?
Maybe the previous owner disabled the light?

Thanks for any help
