Hello and welcome to JustAnswer!

If fuses are good and all lights were lost at once then the flasher would be the most likely cause. It could be a wiring or switch issue and electrical testing would need to be done to know for sure, but a loss of both at the same time without a blown fuse is most likely a failed flasher.

You can obviously try replacing the flasher and see if that takes care of it but you may be able to easily condemn it. With the key on and turn signals on tap on the flasher with something such as a screwdriver or wrench. If the turn signals come on then the problem was in the flasher for sure.

where is it and how do I "tap on" it?what do you mean by "condemn"?if it is the flasher, how do I replace it?
Expert:  sprinkles08 replied 1 year ago.

The flasher is in the relay block under the steering column area. You can turn the turn signals on, key on, and tap on it with a screwdriver, wrench, or something similar.

If an object is condemned that means it has determined to be no longer functional and must be replaced.

The flasher is replaced by removing it from the relay block and putting a new one in place.
