Do you have electric locks? Exactly what did you "unplug"? If you have electric locks, will they lock and unlock with the regular mechanical button?

I understand you may be typing on a phone, but there's no word limit here, we need you to be more detailed and descriptive.

I unplugged the door lock actuator . No it won't lock or unlock with the keys.

More than likely the the door solenoid/actuator has failed. Each door has one and that's what makes the electric locks work. I've had to replace the drivers door twice in my 91 Bronco and the passenger side once. Neither work right now but I have new ones to install when the weather turns warm again. I get mine from Bronco Graveyard online. It installs easiest using a rivet gun but you can fish a bolt with a nut too. If your windows are power and the plastic gear breaks (they last about 5 years), look for the complete motor assembly that have the metal gears. They don't fail. Cost about 60 bucks each.

The tiny BBs inside the early lock motor rust, locking the motor from spinning, OR the latch from working. The later ('92-04) motor is a superior design, and can be retrofitted fairly easily.
