Ok I've posted on other forums and have received very little help. Soo here I go again, My 1996 Cherokee SE keeps blowing fuse #19. I would replace it and the dash lights, 4wd shifter lights, and the heater/ac lights would all work fine but only for about a few hours to a day before it blows again. I tried upping the size of the amp to a 7.5 but it didnt make a difference. I've looked under the dash and haven't noticed any bad wiring or corrosion. Could it be the headlight switch itself? My headlights and all exterior lights work fine, and when I turn it all the way to the left the dome light comes on. There is an aftermarket stereo that I've heard can cause issues also but nothing I've noticed is bad.
Today though I replaced the fuse with a 15, after a few minutes the dash lights went out again, BUT the fuse is not blown... and everything else still works except for the cluster lights, 4wd shifter and heater/ac lights. Can anyone give me an idea of where to look to solve this issue?? What to do to fix it or maybe to try a new switch? Thanks for any help!
