So you guys are telling me the V6 and V8 interior harnesses are different? Or are they part of the engine harness as well? Mines an '02... what do I need to swap in power windows?

2003 Silverado 1500 4.3 power lock manual window truck.
This info only applies to (03-06) (99-02 is plug and play from what I can tell.).I have done some junkyard research on factory power window swap, so far I have found out that the interior fuse box is different (inside driver dash) and the bcm will need to be flashed. So far I have acquired, both front door harness,both door panels with switches, power regulators/motors and the fuse box. I was told by a GM tech that everything has to be installed to be flashed because they also program the master window switch. Gm actually calls the switch a ddm (driver door module). I am currently using after market switches and my stock roll up door panels which drives me nuts. I will post more info once I get the flash done.

From what I understand 99-02 door harness,door panels,door switches,window regulators/W-motor(99-06).You may need to run a wire from inner fuse block to battery.You will notice a 20 amp power window fuse on the fuse block yours will not have it.

Hi, new to this forum. actually 1st time being part of a forum. I am trying to install the power windows on to my son's 2003 silverado v8. It was damaged by a tornado around Christmas week. I have installed the complete door from a 2005 silverado extended cab v8. Took it to the dealership and paid 98.00. Then was told that i need it the newer PDM and DDM from a newer truck. So i bought them But after reading up on them think that is not going to make all the power locks, mirrors and windows work. Any help or Advice??
