Hi,

When you turn the signals on, does anything happen? For example, do the lamps turn on and not flash? Do the hazard lamps work?

Also, since you replaced the flashers, I suspect you checked the fuses. Have you confirmed there is power to and from fuses 4 and 5 in the interior fuse box?

Here is a link explaining how to check:

Now, if you find there is no power to those fuses, then we need to check backward to where the power comes from. The fuses in the interior fuse box receive power from the under-hood fuse box. The turn signals get it from the ignition switch.

I attached schematics below showing the power flow. So, if you don't have power at the interior fuses I mentioned, work backward to the supply.

Let me know what you find.
