My DLRs do not work. I have changed bulbs, fuses, checked relay. LIke others I found the sockets a little burned. I have turned the ignition on and took in out of park during the day. Still not lights. It is like there is no power going to the socket. Does anyone have suggestions as to how to fix this?
Can't get my DLR's to work, sockets look burned. Fuses are ok, bulbs replaced.

They burn too hot. Just bad design by GM. You can switch to LED lamps
