I just noticed this after having my 2005 Grand Marquis valet parked but it may just be a coincidence: When I use my turn signals the hazard flashers come on instead of the turn signal. Any suggestions?

Michele, most systems run on a 3 flasher bases 1 for left 1 for right and 1 for hazard, it should be located with other flasher units, and check your relays.
Probable cause is what we used to call a stacker switch, Your car should have 2 of them, 1 for the turn signals and 1 for the flashers or hazard lights, Normally the turn signal switch is located in the fuse box, a round plug in switch, easy to change and cheap too.
Yes, it does have a flasher, although it may be a combined unit with the hazard flashers relay. So you hear the clicking of the flasher relay? That seems to indicate the relay is working properly. Have you checked the bulbs and the turn signal fuse? Any turn signal bulbs light up anywhere, front or back?
How about your brake lights, do they work? Your car may have separate, stand alone turn signals in the rear, but many American cars use the same bulb and same filament on the bulb for the brake lights and turn signals. If your merc is like this and the brake lights work, then the bulb must be good. Turn on the hazard flashers and see if all bulbs work and flash at each corner of the car. This would be the same bulb as for the turn signals. If they work, it could be a bad turn signal switch, may even be the flasher relay somehow malfunctioning, and in a few cases, a bad hazard switch can affect the turn signal switch. Check fuses and bulbs first. If you have any type of body control module that controls lights and other accessories, you may have to investigate that. I know I'm not being very helpful, just throwing out a few suggestions. Good luck.

there is a flasher
.the hazard is wired to constant power so it works with the ignition off.
the turn signal works off of a switched power,to the turn switch and either the right or left turn signal.
if a bulb burns out,the light stays on steady
