Hi, I have a 93 k1500 and (bear with me while I try to describe the problem) whenever I turn my ambers and/or my headlights as well the right turn signal will be brighter then normal (as if the turn signal is stuck on). It will do this for about 10 seconds then go back to normal. After a little bit it will randomly flicker between dim and bright(sometimes for a second other times I will have to turn my turn signal on to fix it).I checked and cleaned all the grounds I could find. Any suggestions? Any input would be appreciated. Thanks!
