Hi, this is my first post. Had to plow my driveway today with my older chevy pickup. Drove snow up into a snow back, plow went high and four wheel drive suddenly stopped working. Four wheel drive was working flawlessly up to this point. Was wondering if I may have blown a fuse or relay? Anyone out there that can help, much appreciated. All the best.

Don't know about "88" but our "92" has an electrical slave solenoid on top of the front axle. We've had to replace ours a few times due to corrosion.
