Recently my 2003 Dmax 2500HD 15,000 miles lost all power to the drivers side door panel - windows,mirror control, heated seats. locks everything. I checked all fuses then it started to work OK. Drove it a day, shut it down over nite, then it did it again. After 4 hours being parked now every thing is OK again! HELP Any ideas anyone??? I am reluctant to take it to the dealer because I recently had the Banks Six Package installedhttp://www.dieselplace.com/forum/smileys/Disapprove.gif

Sounds like the same problem I had when mine was a couple months old. My was blowing a mid bus fuse. The cure was a replacement underhood fuse block, maybe yours has a short before the fuse. I'd pull the six gun and take it in....

driver door module is my guess 03 I have seen many go down..

Thanks for the feedback on the door module, how do you determine if it is in fact a module gone bad? Am I correct in assuming that is the bank of switches in dricers door arm rest?

yes it is the aka master window switch.to determine is not hard and not easy.you say all function is gone it sounds like the module.you could remove the door pannel and disconect the harness conectors to the module wait say 10 min and reinstall.but your best to get it warrantied
