Turn signals, hazards temporarily do not work.

[gentfarm]

2004 3.0L with automatic trans....Occasionally when I start up the turn signals, hazard flashers and a few of the instrument panel lights do not work. After I drive for a few minutes the OBC dings and gives me its warnings (Check high beams, etc) and thing all operate normally. I put a new battery in the vehicle a couple weeks ago. I also had a new remote key made and programmed as my original fob battery died a few years ago. The dark dash doesn't bother me too much but I don't like driving without turn signals. Any ideas? Thanks.
