Hey everyone I'm new to the site and I cannot find ANYTHING on here about my rear hatch switch on my 93 blazer (full size 5.7L). It used to work when I got the truck and one day my wife went out and tried to open the rear hatch and it wouldnt unlock. So i checked to see if it had power and it didnt. So i bought a power probe 3 kit from my local MATCO dealer. To power up the switch and it worked. So Idk what all of you do to run a new power wire to? Im lost on what to do? Thank you to whoever replies and helps me out! greatly appreciated!
