Condition/Concern

itself. In some cases, the fuse has poor terminal tension and may cause intermittent or completely inoperative conditions for these systems:
–
Liftglass release

Rear HVAC blower
–
2nd row power flip and fold seats
–
Heated outside mirrors

Recommendation/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.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
