Central Locking System- need some help

[dennis]

Ok I have just started to troubleshoot this, but here are the issues:

- central locking light n dash red light on
-when I unlock car horn beeps twice
- horn works intermittently
-passenger door window does not move down when door is opened
-steering wheel locks intermittently
-starter bendix sometimes sticks on first start if day(probably unrelated but didn't know if starter energized longer than necessary couldncause this)

Any help would be greatly appreciated

Thank you
