Coromal Seka 505 - <span class="highlight">wiring</span> diagram / access to wall cavity

Hi all,

Just wondering where I can find out some information on the clearance light wiring of a dual axle Coromal Seka 505 - seems to be a problem near the front drivers side clearance light.

The lights flicker on and off with bumps. When stationary and I bang the wall near the front drivers side clearance lights it flickers as well. Leading me to think there is a wiring issue behind the wall in that area. The same flickering occurs when this light and housing is removed, so it's not a problem with that. The chassis earth under the door has been removed, cleaned and re-attached - same problem.

When all lights are removed from their casings there is still a short between the clearance light pin and earth on the van plug. So the problem is not a disconnected wire somewhere, it is two wires touching that shouldn't be somewhere. All visible parts of the wiring from the vehicle through to under the door side have been checked for shorts. The only place left I can think of checking is behind the wall - eep! Any pointers on how to gain access to that from the outside?

Thanks,
Dave
