4wd will not engage
In a snowstorm yesterday, when I pushed the 4wd Hi button it went on for a second and then flashed back to 2wd and the 4 wheel would not engage. 4 wheel Low worked but not 4wd Hi.
What's the deal?

sounds like problem with mine,under hood remove battery and battery tray,you will see a diaphram with a cable going straigh up through it,check rubber on diaphram if cracked or torn replace 4x4 will work again these vehicles work off of cable,ps dealer part only. about 40 bucks.
