Headlights/turn signal when my headlights are on my turnsignals dont work, but when running in the day with out head lights, there is no problem. any ideas?

Check you running light bulb.. some of those have two elements in them and one side could be blow inside the single bulb. The blinking is how the car tells you that you have a bad bulb, or maybe a short. Mostly likely it just a bulb.

I am just guessing at this one but you might want to check the headlight switch that turns on the headlights. Sounds like you changed just about everything else. The turn signals I believe are on a separate circuit from the brake lights. In addition you might want to check for a broken wire to turn signal harness

Thanks.

My first thought would be a bad ground connection in the harness for the rear lights.
You might want to take a test light and check the contacts in one of the sockets.

The issue is most likely the turn signal switch.

Seems like a huge issue huh?! First have the battery checked 2. check all connections for corrosion around battery area. I'm assuming this just started? 3. if all other things check out good, have the charging system tested for no less than 13.5 volts with all accesories on. Replace the alternator as necessary. Let me know what you find and I'll be happy to continue to advise.

I think you have a bad shorted battery or bad alternator.

four digits in your question

You will need to use a test light to verify voltage at the turn signal flasher.
Turn the key on to the run position, car does not need to be started.
Set the turn signal switch to right or left turn, doesn't matter.
Probe the "purple" wire terminal at the flasher unit. If the turn signal switch is working properly, you will have voltage at the flasher unit.
If you do not have voltage, the switch may be the problem, make certain all connectors to the steering column are fully seated and there are no broken wires.
Good luck and let me know.
Regards,

the circle three prong fuse is the turnsignal flasher and that very well could be the problem. does the signals come on and then not flash or does the signals not come on at all?
