The 4x4 switch on the dash likes to take a dump in those years. They also like to eat encoder motors. If you have a way of checking it, try and get the codes out of the transfer case modual. b2725 means you need a new 4x4 switch on the dash. c0327 means you need a new encoder motor. There are a bunch of other codes that can be in there. But I'll take a guess and say those will be the ones you'll see.
Oh and for what it's worth the encoder motor is the the thing on the transfer case that shifts it. It's a electric motor. And it's NOT cheap! So make sure you find out if it's really bad before you put one in.

SOURCE: my turning signal don't work
since you know where the fuses are, you also know where the flashers are. the flashers are the same part so unplug the one for the emergency flasher and put it into the socket for the turn signals and vice versa. if the signals now work but not the emergency flasher you know to get a new flasher unit at any parts store. the flasher units are cubes about an inch on each side plugged into the fuse panel.

Testimonial: "Just the info I wanted. Thank you! Phil"
SOURCE: turn signals lights don't work
well you need to test for power on the circuit that the turn signals are on, youll need a diagram of the circuit/harness and a multi-meter with the probe attachments that pierce the wire, start at the begging and work back to the lights, when you lose power you find your break in the circuit.
the method you would be using is voltage drop testing. and u can search it for more details on the process
