Here's a badly corroded CLU. This one is not repairable, but yours is in much better shape if the car still runs. It is easy to remove and open up to see the circuit board. There are two forum members that professionally repair these things
ECU Doctors and
Qmulus.
You may be able to get yours working by cleaning corrosion, or it may need to be repaired/replaced. I suspect that you have a stuck relay on your circuit board. It's possible that you can free it up by gently tapping on the little black cubed shaped things (TYCO) on the circuit board. My preferred tool for tapping on relays is the handle of a #2 Phillips screwdriver. YMMV and if a relay is stuck now it will probably stick again.
That's all I've got for today, but the rest of the forum is standing by to assist. Good luck.
