N0 Brake Lights!

1998 Grand Cherokee has no brake lights. Replaced the fuse under the dash and the light bulbs appear unbroken. Anyone gotr any advice? I'm thinking it's the brake light switch above the brake pedal.

the next step would be to test the switch, was the fuse blown?

Take a multi-meter or a 12 volt test light and ensure power is getting to the brake light connectors on the end of the wiring harness.

My tail lights went out, but the cause was due to the tail light assembly and not the switch, fuse or wire harness.

Just my 2 cents.

Thanks for all the great advice!!
the fuse was not blown when i initially checked. so i changed out the brake light switch as suggested by merlintec and everything is now A-OK.
