2001 Dodge Caravan Brake Lights

We are having an issue with our 2001 Caravan. When braking, the left and right brake lights do not come on. However, the light strip above the rear hatch does work properly when braking. We checked fuses & bulbs, but all in good shape. Assuming that since the light strip at least works, the brake switch is also working. All other lights work (taillights, turn, etc). Any ideas what else to look at? Thanks!
