Need to replace signal light flasher can not find old one

I would suspect that it has something to do with the flasher unit. They operate based on current draw heating up a bimetal piece that causes the blinking. Four-ways (hazards) draw more current since there are more filments/LEDs drawing current. By changing from incandescent to LED you have reduced the current draw on the flasher. You may need a different flasher that uses lower current to get turn signals to work. Here is a link that explains it and provides info on how to get the proper flasher.


LED Turn Signal Bulbs Flashing Problems

Sounds like you need a new turn signal switch. And a new flasher relay, just in case your old one got overused! Those little flasher relay cylinders were real cheap back in the day, about $2. It's under the dash around the steering column, probably in a little metal clip (yea, real metal). Don't confuse it with the hazards flasher, both look the same. You can hear and feel the turn blinker flasher when it is doing its thing, and same with the hazards flasher, if you want to check. The clicking is the make and break contact of the circuit to cause a blinking bulb.

The reason I say you need a new turn signal switch is because the brake light signal wire is routed through the turn signal switch before it goes to the rear brake light bulbs. It is inside the turn signal switch that the brakes and rear turn signal lights are made to share the same filaments inside the bulbs. The brake lights don't pass through the flasher, but somehow your turn switch is sending power to the flasher. If the wiring under your dash has not been radically altered, really messed up, then your turn signal switch has got infected with a malware virus: it is worn out and needs replacing. Good luck with that old piece of iron, Greg.

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

are you sure you replaced the signal flasher and not the hazard flasher as they look the same.put the hazards on and check to see if it was the one you replaced.if it is then you need to located the signal flasher and replace it.if you still have the old one you replaced you can use it.

if the hazards flash the problem is not the flasher. Most likley you need a turn signal switch

Replace the turn signal switch

possibly one side of your signal flasher is out turn on emergency flashers to locate one flasher then you can locate the other

The clicking noise is you concern ? I would replace the turnsignal switch or the hazzard switch.

Good Luck

the module can be replaced by a chime or a truck blinker switch from a diesel truck shop and you may here it, however the other guy is right and has a couple good ideals. JC whitnet has one

There is a turn signal flasher on your fusebox it should either be round or say flasher control on it and if your replace this your flashers should work fine. I hope you have good luck!
