94 corolla, back blinkers work but front ones do not

If the front blinkers on your 2011 Lincoln Navigator are not working, but the rear blinkers are, there are a few things you can check:

1. Check the fuses: The first thing to check is the fuses for the turn signals. Look for the fuse box that contains the fuses for the turn signals and check to see if any of them are blown.
2. Check the bulbs: You mentioned that you already checked the bulbs, but it's always a good idea to double-check. Make sure the bulbs are the correct size and are securely installed.
3. Check the wiring: Check the wiring for any visible damage, corrosion or loose connections. Look for any frayed or damaged wires that may be causing a short circuit.
4. Check the turn signal switch: The turn signal switch may be faulty, preventing the front blinkers from working. Test the turn signal switch to see if it is working properly.

If none of these steps solve the problem, it's possible that there may be an issue with the wiring harness or the control module. In this case, it's recommended to take the vehicle to a professional mechanic for further diagnosis and repair.

replace flasher, under your dash, its a round, metal cap shaped unit , try that, also, change your rear bulbs, sometimes the ones that work are the problem, check your fuses also !

Normally with the blinker blinking really fast, it's telling you that one of the bulb is blown, front or rear signals. Check your fuse, and fuse relay to see if it would fix the promblem

Sounds like wrong bulbs in some sockets

Hi mate this is an easy wiring diagram to use and you only have one flasher unit for both flasher and Hazard operations. Sorry for taking so long to answer bit buzzy. I have a circuit stored some where in my brain for a two flasher unit also but this one is the most simplest you will get.

Remember to fuse the Ignition wire. Ask the supplier which contacts are negative and positive on the flasher, don't mix them up you will blow up the flasher. If the dash lights aint working run a wire parrallel to those wires from the circuits left and right (two terminal Type). Some flashers have a build in (three terminal Type) dash signal terminal.

check your wire harness with a voltmeter and check to see if all wires have power. If that doesn't work check your ground wire's.

It is posible both bulbs are blown, I have overlooked this before, if not you will have to change the turn-signal switch (in the stering colume.

replace blinker bulb

have you checked the wire connections to the fround blinker??? when the wire disconnects from the blinker the back blinker blinks faster and the front one doesnt work at all

sounds like your electronic flasher unit maybe stuck causing the noise. they are generally located under the dash on driver side just below the instrument cluster.
