      Hello,

      On the older Jeeps there is a large brown wire which runs between the side on the car and the door in the door jam. It is covered by a black rubber sleeve.

      Over the years of the door opening and closing this wire becomes worn and eventually breaks. Although it is still touching and or making a connection from time to time (sometimes a week sometimes a month) the wire will stretch with heat or cold causing the connection to drop.

      Jeeps run a single wire bus system so when the connection or supply of power to one module is disrupted it puts pressure on the other modules.

      Either take it to a auto electrician (sparky) to have the main feed wire replaced with a more flexible one or give it a go yourself.

      Hope this helps as a start of the diagnostics
