Imagine my embarassment...
Hey friends & neighbors! Want to know how to annoy the @@##**!! out of everyone on a forum? Post a question BEFORE you search, not after! I realized immediately after I started this thread that I hadn't searched, and as it turns out, there are quite a few similar threads already posted.
So anyway, the popular vote seems to be either wrong bulbs or corroded sockets (or both, as would be the case with my car), but what I really want to know is: do the flasher units ever give up? Is it ALWAYS an amperage issue, or are there any other reasons for rapid flashing??
