My turn signals started acting up this morning on my 97 Yukon, and I can't figure out why. The left TS works as normal, but the right TS indicator in the dash acts like it shotgunned a case of redbull and then did a speedball, and the lamps themselves aren't working. The TS module under the dash is for both sides, and since the left side works fine, I assume that the module (what's the correct term?) is fine. The contacts are clean. I haven't had a chance to look at it, but, I'm assuming it's a wiring issue. Any advice as to where to start looking?
