I've been experiencing an ongoing issue w/ the electrics in the Drivers door of my '03 Yukon Denali: Occaisionallly, usually after rain, the driver's seat heater would spontaneously turn on and cycle through it's settings. This apparently subsides when things dry out. A couple of weeks ago, power to the drivers doors appeared to be out, but returned after a few minutes of driving. This occured for several days. Now (again after some rain) there appears to be a complete loss of power to the driver's door:

>keyless lock/unlock function not working on drivers door; all others ok
>power locks not working on drivers door; all others ok
>power window cluster not working from drivers door; all other doors operate ok
>power mirrors not working
>seat heater not working on drivers side; all others ok

Also:

There is no "telltale" chime when key is left in ignition
The radio "delay" function is not working; radio cuts out immediately when ignition is switched off.

I've checked the fuses & relays, and am somewhat stumped at this point.

Anyone?
