Hey there! This is my first post here, but I have been a huge lurker, always coming here for help with my "new" to me 2002 Jetta TDI. So here is my issue: When I first bought the car, the rear drivers side door did not work. No window functions, no locks, and no door ajar light when opened. After some initial research, it looked to be the door control module. I pulled the door apart, and ended up busting the door control module by not being careful. Before I ripped the door apart, I scanned the car with VCDS and got the 01333 code: Door Control Module Rear Left (J388): Defective. I started looking online, and found a 99.5 MK4 Jetta door in black just like mine. I picked that up last night. Before installing the door, I noticed that the 99.5 door only has 1 clip that plugs into the body harness of the car. It is the black clip, containing the larger bundle of wires. My car has 2 clips on the body harness; a black clip (with the larger bundle of wires) and a blue clip (only containing 2 wires; a black and orange, of much smaller gauge). Upon further inspection, it seems that the blue plug controls the tweeter on that door. Correct me if I am wrong there. I installed the door, and plugged it into the car. I tried to roll down the window, and nothing. Nothing on the new door worked either, BUT, now I had a new issue. When trying to control either of the other 3 windows with the 99.5 door plugged in, the other windows will go down roughly 4-6", then stop, and then start again, and repeat that until they are all the way up or down, as long as you are holding the switch. When the 99.5 door is unplugged, all 3 windows operate properly. What is the issue here? I doubt it is anything simple, but I am up for a challenge, and I have extensive mechanical knowledge, and a fair bit of electrical knowledge. Somebody help me out here! Summer is on its way, and I want to roll that dang window down already!!!
