the fuses can fool you if they are the ones with a paper inside, so try replacing the fuse even if it looks good.

I take it you checked the Stop Bulbs? (the upper ones).

Next step is to remove the lenses and then eachtail lamp assembly to check the large Plug connecting the assembly to the wire harness. Take the plug with both hands and "twist" each half in a different direction while pushing them inwards, to make sure there is good contact everywhere. Also check the rear contacts in the tail lamp assembly.

Next check is the wire connectionsin the Brake Switchlocated under the Brake Pedal. (because you never know...)

My question is: Do the Driving lights go On ? (the Red, normal, "driving" light).

let us know what happens.
