Signal fuse keeps blowing

There should be on on the fuse box under the dash, and another behind the radio. The one on the fuse box usually handles the emergency flashers.
You might want to use the emergency flashers to make sure all of the bulbs are working.

Usually it is a bulb because it takes all 3 or 4 to make the flasher work. Not all bulbs have to work for the emergency flasher.
If all of the bulbs are in fact good, it could be the turn signal switch.
On rare occasions the flasher is the problem

IF TURN SIGNAL LIGHT DONT WORK SOME TIMES.CHECK FOR BLOWED OR LOOSE FUSE.CHECK TURN SIGNAL BULBS AND CHECK BULB SOCKETS FOR CORROSION.CHECK TURN SIGNAL FOR BAD GROUND.USE JUMPER WIRE BETWEEN GROUND SIDE OF THE TURN SIGNAL BULBS AND A GOOD CHASIS GROUND.IF ALL IS GOOD TURN SIGNAL SWITCH IS BAD OR FLASHERS GOING BAD.TURN SIGNAL FLASHER LOCATED ON CENTER CONSOLE SIDE PANEL GRASP THE FLASHER UNIT AND DETACH IT FROM THE FUSE BOX.IF YOU HAVE EARLY MODEL VECHICLE FLASHER UNIT LOCATED AT THE FRONT OF THE FUSE BLOCK.

sounds like the hazard light flasher is bad that is why the signals won't work as for the heater check al heater wires and connects for melted wires there is a short to ground some where.Also check heater blower motor resistor could be burned out .

there are two flasher for this car, one for the hazards and one for the turn signals, the turn signal flasher is located behind the center of the ashtray,the hazard light flasher is located on the fusebox center.this fuse center is located behind the right side of the dash to the right of the glove box, hope this helps.

The Flasher Relay is more than likely defective. Replace it. Turn signal flasher located Front seating area, driver side, under dash, mounted on passenger side of steering column. Curtorsey Auto Zone

Check all the parking light bulbs and sockets - this is usually a sign that a bulb is out or you have a bad socket

My turn signal flasher was located to the right of the ash tray, I looked around the column for HOURS and it wasn't there... I also have an 93 oldsmobile cutlass ciera, it drove me crazy because the manual wasn't correct.

under the dash on the driver side there is a round or square sliver box that should say turn signal or flasher on it in the fuse box.

I think its under the hood in the main fuse panel, its a round 2 or 3 prong silver looking flasher switch about as big around as a half dollar, bout a inch thick.
