I changed the bulbs in both front and back and it still won't blink and the light on the dash stays on. I'm told to check the relay but can't find the fuse box under the hood or inside the car. What are your thoughts or suggestions? Do you think it can be the fuse, relay or the entire signal switch?

Hi,

Do you mean the indicator lamp in the vehicle is on at all times regardless of the signal switch position?

As far as a no flash, there is a signal flasher under the dash near the instrument panel fuse box. See pic below. If they are simply not flashing, this is what the likely cause would be.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pic.

Okay, so, I found the flasher relay and it seemed to be not pushed in all the way so I pushed it in and nothing changed its the passenger side turn signal only that's not working even after bulbs are new and fuses are good also the emergency flashers work on both sides all lights work all around accept the right (passenger)signal and its dash light comes on and goes off on its own but never blinks and when the switch is put to turn it off it won't go off until it wants to the pics below show you that all lights work other than that 1 light. So, now can you give me your thoughts on where to look next or do you think it's the actual switch on the steering wheel.

Hi,

Based on what I see, either the flasher is bad or there is a short. However, I feel it is likely the flasher. There are two circuits in it and it appears one has failed.

Let me know.

Okay, so, I see where the flasher plugs in at and the wires coming from it. So, is it a part I can buy and if so, how hard is it to replace? Also, would the hazard lights still work if the flashers bad cause both sides blink when the hazards are on.

I thought I should mention that regardless of if I hold the signal switch up or I f I click it to get the light to blink it doesn't, it gives no light or any blinking on that side other than when the hazards are on and this is both in the front and the back of the car however the signal arrow on the dash will come on and stay on as well and will go off on its own as well.

Hi,

The flasher should be available at any parts store. Also, it is very easy to replace. It is clipped on the sound insulator and will have an electrical connector. Remove the flasher, unplug the old one and install the new one.

Let me know if that takes care of the issue.
