blinkers on 95 s-10 blazer

[shorefisher]

Have a 95 blazer and the turn signal and hazard 4 way's not working. The bulbs are good, all other lights work. They do not light up on the dash at all, fuse is good. What would you look at next flasher(s), relay or ? Any and all ideas would be great. Thank you.

There are seperate druses and separate relays for the turn signals / flashers. If both of the fuses are good than la ate the flashers in the convienience center under the dash I think. There should be power on one side AT&T the time and power on the other with the flasher plugged in. This will be true with either flasher.

The most likely problem is the switch itself. Are you sure you have brake lights? If the turn signals and brake lights are both not working than I guarantee it's the switch. Usually you can wiggle and jiggle the turn signal lever and get something to work.

Yes I am sure I have break lights. I have wiggled the switch but nothing. What seem funny is that the dash arrows do not light up. When ever I have has a flasher of switch out the dash arrows would still light just not blink. I was told to check the two relays in the glove box and there are two fo them but not marked so not sure if that is what they were talking about small black plug in relays (I also have no idea how to check them?).

The flashers should only have 2 pins. with either flasher removed there should be power on one of the wires all the time. This is the hazard flasher. The other flasher will only have power on one of the pins with the key on or the engine running. If the flashers are indeed 2 pin flashers and there is power on one of the pins jump the connection with a jumper wire and try the turn signal/hazards. if they work the flasher is bad.

The other wire for each flasher goes to the switch. You can pull the steering column covers and check for power at the purple and brown wires. If there is power there the switch is bad.

Once power enters the switch it is routed through its particular function. Whether it be right turn. left turn, or hazards. Power the proceeds to the turn/brake part of the bulbs and the turn indicators.

There are only three possibilities that would make your symptom occur.

1. Both power supplies to the flashers fail at the same time.

2. both flashers fail at the same time

3. the turn signal switch has failed.
