Does the 77 corvette have 2 flasher fuses and where are they located

In the picture below the arrow points to the courtesy light fuse.

check under dash put hazard lights on while looking ,it should be close by the one that's clicking.

Should be under the drivers side dash.. turn the key on.. turn on either the hazards or turn signal.. the flasher unit is plugged into the fuse box.. you will hear it.. helps locating it.. unless of course this is what you are replacing!

Good luck

It sounds like you have a wiring problem. get a volt meter and locate the fuse box. First check your fuses. If everything looks ok there take your volt meter set on DC and check each fuse if one of them reads low or doesnt read at all then you have a wiring problem.

HI. This pictogram will help you with your firing order for your 77' Corvette.(350).
Great Car!

it should be plugged in the fuse box,it is a silver round cylinder

It is the button, the top of the dash needs to come off to remove the switch. It isn't as bad as one would think. Lots of screws but strait forward.

passenger side near the back of the engine.it bolts to the transmission housing.the bolts go up into the the transmision housing.

Fuses are located in the junction box below the instrument panel to the left of the steering column. The turn signal flasher and hazard warning flasher also plug into the fuse block. Each fuse receptacle is marked as to the circuit it protects and the correct amperage of the fuse. In line fuses are also used. Refer to the Fuse Chart at the end of the information for their location. The fuse block on some models is a swing-down unit located in the underside of the instrument panel adjacent to the steering column. Access to the fuse block on some models is gained through the glove box opening. The Convenience Center on some models is a swing-down unit located on the underside of the instrument panel. The swing-down feature provides central location and easy access to buzzers, relays and flasher units. All units are serviced by plug-in replacement. Location of Convenience Center on specific models may vary.
