Chevrolet Repair: 1988 chevy silverado 1500 4WD 5.7 engine, chevy silverado, move check


Question
where is the fuse for the 4WD? what activates the actuator to engage four wheel drive?

Answer
Hi kathy....fuse for the 4x4 should be under the hood in the power control centre....if fuse is ok check t see if the actuator on the transfer case is stuck...it is common problem...tap it lightly if you think it is stuck...if still doesn't move check the plug for power when you push 4 hi button..if no power and the fuse is good check the 4x4 module....hope this helps
