The 4WD is engaged with a vacuum switch, so the first things I would check are the vacuum lines that go from the manifold to the switch and from the switch to the transaxle.
If you don't have a repair manual, probably the easiest way to find the lines and switch would be to locate where the lines attach to the transaxle. There is an unusual extension coming out of the passenger side of the transaxle. It is between the engine and the firewall. It is a metal extension with a kind of circular disk shaped end. There should be two vacuum hoses attached to the extension that lead up to the vacuum switch. The vacuum switch is attached high on the firewall.
Check the lines for cracks. I usually just replace them, since it is very easy to miss a crack or leak. The switch can be tested by applying 12V to individual solenoids in the switch and checking to see if they allow air-flow through the valve.
We can probably get you pictures later if you need them.
