try the hazard lights. if they work check the bulbs with them working. if good and the turn signals not working then it could be the signal flasher is bad. witch out the hazard flasher for the signal flasher it they work then replace flasher, or the turn signal switch it bad.
There should be a turn signal flasher and a hazard flasher. They are two different parts. If you replaced the hazard flasher and not the turn signal flasher than I would start by replacing the turn signal flasher.
One thing you can do once you find the turn signal flasher is to unplug it and use a jumper wire between the two pins of the connector then turn the key to the run position and place the turn signal lever in the left or right position. If the turn signal lights know light up than the turn signal flasher is the problem
the flasher is under the dash on the drivers side. if you turn on the hazard lights and look under the dash you will see what turn signal flasher looks like and know which flasher not to change thinking its the right one. look for the signal flasher and change it.
located under dash to left of the steering colume. note there are 2 flasher relays one for the emergency flashers and the other is the signal flasher. to know which one is the signal one turn on the emergency lights and look for the flasher the one that is clicking is the e-flasher. the signal flasher looks the same locate it and replace.
the signal fuse is in the fuse panel under the dash to the left of the steering colume. and the signal flasher is under the dash same side as the fuse panel and is a square or round looking unit with a 3 wire plug connected to it. make sure you have the signal flasher and not the emergency flasher as they look the same. to know turn on the e-flashers when your think you`ve found the signal flasher, if you have the signal flasher you won`t feel it ticking .
On my 95 Chevy 1500, the 4way flasher is located in fuse panel on firewall driver side under dash. To get to the turn signal flasher, remove the bottom dash panel and the entire ash tray compartment. I also removed the cup holder unit to allow light. The turn signal flasher was located just below the the radio and AC area. Mine was wrapped in tape from the factory, but if you turn the turn signals on you will feel the vibration and be able to locate it from the sound.
the flasher is right below the radio,under the dash .it take 3or4 screws to take off panel.both flashers are under there.one for your 4 ways,and one for your turn signal.if your four ways work you can fill the flasher to determin which is witch. mine the four ways was on the left,turn signal on the right.they are not in the back of glove box.ther is apanel there with three relays but not for your turn signal.thank u gm jim.u helped me find them.
The fuse panel is located under the instrument panel to the left of the steering column.
The hazard and turn signal flashers are located on the relay module.
HOPE this HELPS EASY way to DETERMINE witch one is for turn Signals is to Turn ON HAZARD FLASHER and this shows that the other one is for turn Signals PLEASE REMEMBER TO RATE ME MOST FOLKS DONT remember to. THANK YOU AND GOOD LUCK
If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.
Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
