blowing fuse for pwr lock and mirror
 

My lift glass tailgate comb stopped working. Checked plastic actuator piece and its good. Checked for power there was none. Also lost per locks and mirrors at same time. All fuses were good relays until I took back panel apart on tailgate. Now blows fuse for per locks and mirrors. Even tried a 5 and 10 amp fuse blew them before I got in all the way. 2000 blazer zr2 2 Dr.
