If the overdrive switch on your 1988 Ford Econoline E350 is not working, it could be due to a faulty switch, a blown fuse, or an issue with the transmission itself. First, check the fuse associated with the overdrive system. If the fuse is fine, inspect the switch for any signs of damage or loose connections. If those components are functioning correctly, the issue may lie within the transmission or its wiring, and further diagnostic testing may be necessary.
