How to be sure relay has gone bad: checked fuses all are good,hazard and turns don't work but running lights do,when hazard switch is on nothing happens,when hazard is off all turns light up so i'm thinking its a relay

Double and triple check the fuse for your rurn signals both visually and with ammeter to check for fuse continuity, or just replace with new one of same amperage. The fuse can look good but have a hairline crack that is not visible.

YOU MIGHT HAVE A BURNT OUT RELAY IN FUSE COMPART UNDER YOU CARS HOOD CHECK THAT OUT THRU YOUR CARS MANUAL,IT WILL SHOW YOU WHICH RELAY IT IS?

Had the same problem, check your fuses, my was out, changed it, works good Good luck

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 unit for the turn signals, separate from the hazard flasher, that is under the dash. If the fuse for the turns is good, and you already know the bulbs are good since the hazards work, then you may have a bad turn signal switch.
When you use the turn switch, do the bulbs come on and stay on, or nothing? If they come on and don't blink, then it's probably a bad turn flasher unit. If they don't come on at all, suspect a bad turn signal switch. But first check the fuses, then pull off the connector to the turn switch and see if you have one hot wire there, with key on. That one hot wire will be from the fuse.

OK try this, push and hold brake then push on the hazard switch if brake lights come on then replace the turn signal switch.

See picture below of drivers side fuse panel and run these tests at the relay holder pins:

E is ground...measure resistance between it and ground (someplace else on the car) to make sure it is 0 ohms or at least very close to it.

B terminal should be 12 volts, if not, you might have a blown fuse (#1), or a faulty hazard switch.

Short B and L and flip hazard switch. If nothing happens, bad #20 fuse, bulbs, poor ground, bad hazard switch, or cut wire.

With B and L still shorted, flip turn signal either direction. If nothing happens, you have bad signal switch.

If all tests pass, the relay is bad.

if the emergency lights are working the we can eliminate the relay because it's a combination relay for both turn signal and hazardous lights. you need to check the fuses, it's more likely the problem. it won't hurt to make sure if the bulbs are ok

Ignition switch will cause you to loose your head lights and turn signals. You will still be able to start the car and hold the switch for your brights but normal function is gone. Check it out it usually only runs about $20-$30 for replacement part but you need a special puller to get to it.

96 eclipse rs back tail lites and dash wont come on i changed the combination switch ,fuses,relays and bulbs and it still dont work what else can it be?
