The other day when I was in Alex my cars scerity system became a complete mess. For some reason the hole system became a complete mess, well first the keyless entry would not function so I had to use the key to unlock the car and when I opend the door the dome lights did not turn on (for any of the doors), The power locks will not work, Well I went to tart the car the horn would give a quick tone just a beep than imedeatly after the horn would go off for about 30 seconds contunious (kind of embarrising, a bunch of ppl were looking at me). This happens every time I put the car in run, but the car still starts. I can get the horn to shut up by pressin lock but starts up again after I let go untill 30 seconds is up. Well I made it home but the probem still exists. dome lights still wouldent work but the info center shows when they are open anyways once I got home my friend noticed a clicking noise, it started to get louder with time now I can fel it in the floor whn the doors are open and when I sound the horn the lights on the climate controll and radio go out for a second, whats the Problem?

Sounds kind of similar but I can still get my interior lights to turn on with the switches, and how do you explain the horn issue.

Well my dad brought the car to a mecanic, sadly enough the mecanic is looking through books trying to figure it out (kind of sad)

It'* acting very much like a bad ground, especially when operating one device (e.g. the horn, in this case) has an effect on other devices. This shows that current is not flowing in the directions it should be going, and is instead seeking a ground path through other circuits.

Have your mechanic start by checking every ground connection he can find, starting with all the battery cable connections.
