Title: Right turn signal buzzing
Post by: gravyface on May 24, 2011, 11:10:29 PM
Hit a bit of a bump, right turn signal immediately stopped working and is now omitting a wretched "eeeeeeee" buzz sound when on.  Left works fine.  Relay?  Fuse?

So I've replaced all the bulbs (PO put wrong bulbs in the rear; contact on bulb had a groove melted in it) and keep blowing fuse #4 (tried pulling fuse #25 too as read that hazard switch can be a cause of this).  Left works ok, right signal makes an awful "eeeeeeeeeeee" sound coming from the dash or steering column.  Never heard anything like it before.

Any ideas?

I'm just guessing here, but that sounds like the undervoltage relay is kicking on.  Check the wiring for a short, especially on the one with the melted connector.  I'd also check to be sure the battery has over 12vdc.  If you have a body harness short it'll be draining the battery quickly.
