Please discard PIT5317C. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition / Concern When working on any of the systems listed below that receive power from the rear body fuse block (1), inspect for loose fuse connections inside the fuse block itself. In some cases, the fuse has poor terminal tension and may cause intermittent or completely inoperative conditions for these systems: - Liftglass release Liftgate release Power liftgate Rear HVAC blower 2nd row power flip and fold seats Heated outside mirrors Rear heated seats Rear wiper Recommendations / Instructions Note: Disconnect the negative battery cable when performing this procedure. Using the "purple" J-35616-35 test probe, check for proper terminal tension at the suspect fuse (2). If poor terminal tension is found, first remove all the fuses and relays from the fuse block. Then, remove the white cover from the rear body fuse block (3) by releasing the three retainers on the sides and bottom. In many cases, the loose connection is on the main power buss bar (4), inside the rear body fuse block. If the loose connection is found to be with the main power buss bar (4) or the plastic fuse block body is deformed, replace the complete Rear Fuse Block with GM Part number 13586872. The new Rear Body Fuse Block will include the main power buss bar and the black plastic body, shown below. All fuses/relays/terminals will need to be transfer over from the old fuse block. If the loose connection in the rear fuse block, is found to be something other than the main power buss bar, replace the appropriate terminated lead listed in SI.
