The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.
Condition/Concern:
Power door locks, power outside rear view mirrors and rear hatch (utility) are inoperative.
Recommendation/Instructions:
Check the underhood fuse block for the 3 amp MIR/LKS (Mirror/Locks) fuse being blown. Note that the label on the underhood fuse block calls for a 3 amp fuse as does SI. Engineering has determined that in some cases a 3 amp fuse may blow. If the 3 amp
mirror/locks fuse blows it can be replaced with a 5 amp fuse. This will provide ample protection without causing damage to the circuit. Do not use any fuse rated above 5 amps.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
