The power door locks will not work unless the key is in the lock

My Chevy r10 power door locks will not work unless the key is in the lock. And even when it works. The key will only come out when it is unlocked. Help?

Ethan , this 1987 vehicle has more problems than can be solved without actually being able to examine the vehicle . Who know what kind of lousy work arounds have been done to it in the past.
