How to replace Turn signal in 2000 Toyota Corolla

does your car have the signal light flasher if so find it and replace it also check the fuses maybe both sides are fused separate

Do your flashers work? If not it may be the flasher unit is bad. It is located under the dash on the drivers side on or near the fuse box. If the flashers work you may have a problem with the turn signal lever or the wiring connected to it.

Assuming the fuse for the turn signals ia not blown, it sounds like the flasher unit is faulty. most vehicles have separate flashers for 4-ways and directionals so one may work while the other doesn't. Sorry, but don't recall the location of the flasher for that vehicle, but a parts store should be able to look it up for you.

Do the flashers still work? This sounds like a bad flasher relay problem.Locate the flasher for the turn signals and hazard lights. The flasher relay is under the dash near the steering column. It will be the larger of the square relays.Try wiggling it to see if turn siganls will work or emergency flashers will work. The relay should look like this

Yes, you are on the right track. More than likely it is a defective flasher relay as one relay controls turn signal and hazard flash. The flasher relay is located behind the left side of the instrument panel.

change the fuse AUX.

it located near the battery adjacent to the fuse box

Hi, i recommend testing the switch and flasher module. i will post the testing procedures for both devices. replace the device that is faulty.

To test turn signal switches, use a 12-volt test light to probe for voltage into and out of the switch. The ignition switch must be in the RUN position for the circuit to operate. If voltage is present on the input side of the switch but not on the output side, the switch is faulty.

FLASHER TEST PROCEDURE---

• A test light can be used to determine which flasher is used for the turn signals and which is used for the hazard warning light.
• An easier way is to turn on both the directionals and the hazards. This activates both flasher units.
• By removing one of the flashers, the affected circuit no longer flashes.
• Therefore, that flash unit controls that particular circuit.
• If the turn signals fail to operate and the fuse is good, the flasher has probably failed.
• Occasionally, the flasher does not flash as fast as it once did, or it flashes faster. This is also cause for replacement.
• If it flashes too slowly or not at all, check for a burned-out bulb first.

the flasher is located in the Front seating area, driver side, driver side of steering column, mounted in corner behind instrument panel

If the turn signals operate properly in one direction but do not flash in the other, the problem is not in the flasher unit. A burned-out lamp filament will not cause enough current to flow to heat the bimetallic strip sufficiently to cause it to open. Thus the lights do not flash. Locate the faulty bulb and replace it.

If the right side signals are working properly and you can hear the signal flasher clicking when the right side signals are selected, the flasher is not the problem. Its more likely you have a short to ground in the left side wiring somewhere.

Try the fuse/breaker panel under hood, drivers side.
