    turn signal lights do not show on dash but fuses look ok.

    I found out how to fix this. As unbelievable as this sounds, I read that a gentleman had fixed this problem by spraying wd-40 around the flasher button and pushing it in and out a couple of times. This worked and it is fixed.

Check for broken Lamp near the point of impact If the light comes on on dash but doesn't flash. If dead check the fuse for turn indicator lamps can be found in the owners manual

    You need to check the fuse that supplies the turn signals for voltage using a 12 volt test light or meter( be sure to check both sides) If one side has power and the other doesn't the fuse is bad. Also check the flasher located in or near the fuse panel under the dash. If this doesn't work,You will need a shop manual with a wiring diagram and the know how to preform electrical circuit analysis.

Wher is the Flasher Relay on a Mercury Grand Marquis 2005

It is built into the flasher. The button you push. If it is in the dash, replace it. If it is in the steering column, replace the turn signal switch.

Flasher relay in a 98 mercury grand marquis?

The fuse block the relay is located in is behind the knee bolster, the trim panel under the steering column, left of the steering column underneath the dash. Common source of problems if that does not fix it is the Light Control Module ( LCM), turn signal switch unit, headlight switch.

Brake lights and turn signals quit working

The first thing to do is check the fuses, the fuse may have blown, maybe to a short or bad bulb, start with the fuses and also make sure the 4way hazard lights switch is off.

Stop and TS problem

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

Turn signal don't work or the flashers?

If you still have flasher problems, I read on Google to spray WD-40 down in and around the hazzard flasher button, then press it up and down several times...and BINGO...all flashers and signals worked again....just had some dirt and dust in the wiring....
