I have a 2006 F-150 XLT 4x4 and my left turn signal all of the sudden started to flash way faster than the right. It's almost like a strobe light..Any info on what this problem could be or a way i could fix it? thanks in advance

 

probably have a burned out bulb. 5$ at any parts store. pick up a haynes manual while your there. it explains everything in detail.
