98 E320 Intermittent Electrical Problem from Center Console
 

I am randomly losing all three functions (windows, trunk release, and outside mirrors adjustment) from the center console. Windows are stuck up at the moment. From outside the car the key control will operate the windows, sunroof, and trunk release.

I'm thinking a relay may be at fault, or worse yet, the legendary intermittent cable harness problem. This car is really wearing me down with frequent electrical problems.

I would very much appreciate any ideas/help. Thank you kindly.
