My name is ***** ***** I will assist you.

There is a short in the wiring and the hard part is finding it.

I jave a document that I will post in how the system works and areas to check. I have to go through my files to locate it.

In the mean time, may I get the full VIN of the vehicle so I can get the wiring diagram for you as well? Thanks.
