Ive done a search and can only see threads about people not getting them to come up... but sometimes when i turn my lights on, the light covers just keep going up and down non-stop... So fking annoying I wouldnt even know where to start looking? Any suggestions where i can start?

I had this problem once right after i washed my car, cause the relay for them got wet im guessing. It went away once it dried out and hasn't done it since, if you search you should be able to find some threads on it..well i did when it happend to me.

the special relay for the flip ups, as above if they get wet etc they cause this it's a fairly unique part, from memory it's in front of the battery
