Pull the lower cover under the steering wheel and check the plug connections for the Multi function Switch (Turn, cruise, etc) on the Left side of the wheel. There was a recall issue with overheating of the switch connections and melting of the connector causing electric havoc. No ground for turn signals, radio, dash lights, etc.

Advice-remove the Multi function switch stalk and break apart the plastic of the connector and do the same on the wheel side if it is also melted.. Free up the spade connectors within the plastic and replace any needed with crimp on male and female spade connectors and wrap all with tape and reinstall the Multi function Switch by plugging each connector into its mate.

This is a known Ford Ranger issue and typical of FoMoCo electrics. Remember they had faulty ignition switches that would short and burn your car to cinders in your garage but FoMoCo said it was no big deal!

Thanks.
That has the sound of authenticity.

Hope this works!

I had a 02 Ranger with the same problem and this fixed the issue.
