hey, i have an owners manual right in front of me for my 98- It shows the air ride fuses is in the power distribution box under the hood, there are 2 fuses, a small 15A in location 4, and a large 60A in location 13. Both are labeled SSM.
Note that while the number 13 larger fuse is designated to strictly air ride, the smaller one also controls "Electronically variable orifice power steering"
hope this helps
