I drive a 99, 2500, Quad Cab, Long Bed, Auto, 4x4 with 328,000 on it. It is a great truck. Recently it has developed what I like to call intermittent turn signals. Sometimes they work perfectly. Sometimes they blink 4 times then stop. Sometimes they blink once and stop. I replaced the turn signal switch, and unfortunately that did not solve the problem. Does anyone have some words of wisdom for me, or could you point me in the right direction? Thanks so much!
