I have a 4X4 Ford Ranger XLT 98k mi 3.0 L V6, When on the freeway or anytime I have my cruise control on, If I turn left turn signal on the Cruise control will shut off and the transmission down shift's, the downshifting will happen with out cruise control on and not to the right turn signal it downshifts every time I use my left turn signal as does the cruise control only shut off to the left turn signal ; the turn signal is also the dimmer switch the part that bothers me is that I have no bright lights.
