Both front blinkers are not working (bulbs ok)What do check now? on 2000 Lexus LX470

Back blinkers work fine. hazard switch blinks only back lights as well.

There are a couple of things you can try. First try putting a little vaseline on the bulb and try them. If that does not work, check to see if the two contacts in the bottom of the socket is up far enough to make contact with the bulb. If not remove socket and push wires up from behind to expose more of the contacts. It that still does not work, you may need to replace both sockets.
Thanks, but for some reason the electrical signal is never even reaching the bulb socket. Any more ideas?
