2007 DTS DDM - no power to door

i have a 2007 DTS i have no power to any of the switches on the door panel nothing in the door works mirrors heated seats even the turn signals in the mirror don't work and the door light at the bottom does not come on either .i have checked the fuse and i am getting power to both sides of the fuse i also pulled the panel and tested it for power i am getting power to the automatic door locks but they do not work either .all of the other doors work and have power but the drivers door ,i had pulled the fuse for the drivers DDM and put it back in and power to the door came on for about a minute enough to get the window rolled back up but then nothing again all power switches don't work ,also were is the DDM on the 2007 model is it with the power switches in the door or is it separate ,if you let the car sit sometime the power comes on to the door but last only a minute .also i heard some crackling coming from the door like something was shorting out this i heard the first time it happened but i checked all wires and none are burnt and i did not smell anything burning so i think it may have been coming from the speaker detecting something but it did sound like it was coming from the switches .would like to get this fixed if someone out there can help .also concerned because i keep the car in the garage and don't want it to catch fire and catch everything else on fire
