Blinkers Aren't Working--Weird Problem/Fix

Hey Y'all,

I've been dealing with blinker problems for the past two years. In the mornings my blinkers would never work, but by the afternoon they would work fine. I assumed it had something to do with the humidity/moisture.

I brought my truck to the Toyota dealership and they looked at it for a week and could not find a problem.

This weekend my truck's blinkers didn't even turn on in the afternoon, so I started checking relays and fuses. I turned on my caution lights and they worked. Then I tried my blinkers and they started working.

This morning I hop in my truck to head to work. I turn on my blinkers and they don't work. I hit the button for the caution lights and they turned on. I turned them off and hit my blinkers and they worked.

Any idea of what the problem could be?

 

Could be a week flasher unit. Kinda hard to get at, from what I've heard. It is attached to the inside fuse box behind the dash near the driver's left knee.

 

I posted here with an intermittent problem and the below worked. For $12 it is worth a try

All of the wiring for turn signals passes through the hazard button, so it's possible there is a loose connection there. More likely that you have a weak flasher unit and the higher amperage draw of the 4 flashers being on kicked it into gear for a bit.

 

damn that blinker fluid.

 

I had a similar problem. Turned out my hazard button was stuck half way in between on and off. Pulled it out and everything is good now.

 

Yup! Same deal here. I noticed too that if you press the hazards half way down, it activates the either the left or right turn signal. Wierd.

 

You've heard wrong. 5 seconds to swap one out.

 

I had the some problem on my 04 Tacoma , after trying everything I found out That the problem was that taillights were filled with moisture and the connections on the bulbs were rusty and contact was weak or wasn't happening , I replaced bulbs sanded the connections with a pick and sand paper, used a lot of dialectic grease since I didn't want to buy new taillights , fixed the problem
