Can someone tell me if the 4x4 in this 1990 Bronc II with push button on demand is vaccuum operated?? meaning if it doesn't respond there is at least the potential for the problem to be a vaccuum line failure/leak?? Thanks for any input in advance.

I thought it was electrical but did suffer from connection problems that are easily fixed. Find the connectors and clean them and see if that works.

If you do not get 4wd and you have an electric Tcase 9 times out of 10 the problem is a corroded up or burn't out motor on the Tcase.
