I'm having a problem with my blinkers. With the headlights on---the blinkers come on but do not blink. In the daytime---without the headlights on the blinkers work fine. ---Any suggestions would be appreciated.

One of the filiments might be burnt on your dual filiment bulbs. check that first, then try replacing the flasher unit.

Bad grounds, probably at the tail light sockets. Take them all out, and use sone sandpaper on the housings and the metal tabs on the sockets that touch the housings. The fronts ground with wires that bolt to the rad support, make sure they're connected too.
