The hazard and signal flashers are located behind the plastic lower dash panel, aprox under the radio. The lower dash panel must be removed to gain access to the flashers.
If the turn signal bulbs light but will not flash, the flasher relay is defective, replace it.
The flasher is part of the hazard light switch.
the hazard light flasher relay is bad
find your fuse panle under the dash look at the lower right corner flasher switch is there,it is silver,light green or black plastic.the num. 225 should be on it
How do you reset check engine light for the 2009 Chevy trail blazer?
how do you replace dome light in s10 chey blazer?
Built in in the hazard light switch.
The flasher unit is contained inside the hazard light swith on the dash. You need to remove the dash panel and pull the switch out from behind. The entire switch must be replaced which is about - at a Chevy dealer.
No flasher. Relay in the cluster circuitry emulates the sound of conventional flasher. The circuit is mux ( module controlled)
Sounds like there is a problem with the turn signal switch but it could be another problem. First you need to see if the hazard light's work normally when turn signal is not on, if it does the the turn signal switch is the problem. If your hazard lights do not function when you turn the hazard light switch on, then it's a simple fuse or flasher canister that has gone bad and your hazard flasher is in the on position. If the Hazard light's have a bad fuse or flasher canister and is in the "ON" position it can cause the problem you describe.
the signal flasher is the hazard light switch......remove the radio bezel and change the switch
Probably the turn signal/hazard flasher went bad. On some vehicles they are separate units, but on some vehicles they are the same unit.
