Blinkers flash fast when brakes applied

Third brake light stays on and flashes when turn signals activated. Apply blinkers and cruise control disengages. Checked fuses and found a 10 amper blown to the right rear brake light, replaced, no fix there. Any ideas? Maybe the BOO switch? All other lights work fine, no problems with multi-function switch. HELP! 2007 F-150 King Ranch. P.S. Replaced brake on-off switch with a known good one...No fix there.

Speed control always cancels when the brakes are applied. Think about it.

You have a filament crossed in one of your rear taillights. Replace the bad (or both) rear taillights and this should resolve your problem.
