I had this same problem on my '95. Check the vacuum lines that run on the top side of the firewall and go down in between the brake booster and the fuel shut off solenoid. Just trace them to find any breaks or something that came unplugged.
One of mine broke in half and caused my vents to be stuck on defrost, 4 wheel drive didn't work, cruise control stopped working, and my emergency brake and ABS lights were stuck on. Added an old piece of windshield wiper hose to patch up the cheap plastic vacuum line and everything started working again . Hope this helps!
I tried to find an image to help where they are. But no luck. I know they are stiff plastic lines with rubber T's and elbows. Just be careful not to break them because they are very brittle. At least mine were!
