    I have power everything on this truck.
    The pdl and pw work only when the car is in park. When in drive, none of the buttons on the drivers door work, however the ones on the passenger door work all the time.

    The truck has not been in any accidents. no fuses are blown.

    Sometimes, after driving for at least 10 minutes, the drivers door power buttons start functioning again.


    Thanks in advance for any help.

    Hi, I think It could be BCM (body computer module) problem that might need to be reprogrammed. I suppose you probably will have to take it to the dealer and have them reprogram BCM. It might have something to do with security problem.

    If it only affected the PDL's I wouldn't disagree but the fact that it also has a PW issue (which are in no way tied to the BCM) I would likely suspect a broken wire in the pass-thru harness in the door jamb. Happens more than guys realize.

    i hate going to dealers for anything, for the most part they are useless.

    I will take to door apart and check all the wires including the pass through and let you guys know.

    Thanks for your insight.

    I agree with you on checking the wirings through door jambs. Power windows and power locks does go to BCM (body control module). I checked on Mitchell Ondemand5 online this morning and looked at wiring schematics and they both are routed to BCM.

    Dumb question, but where is the BCM located?

    I checked and couldn't find any bulletins. There was mention of something similar on the passenger side and said to check grounds for the PDM, but that's it. Thought I'd let you know.

    But only for the RAP (retained accessory power) function which doesn't come into play while the ignition is in the run or accessory position. :salute:

    Do you have any friends who might have Tech 2 and check to see if any problems show up on it? Might give it a try.

    unfortunately no.. I hope someone in NH or MA who reads this might be able to help.
    I will drive 100 miles if I have too.

    Update

    Well, wanted to tell everyone how I finally fixed the PDL and PW issue.

    I removed the drivers door panel and checked all the wires, traced them thru the door jam all the way to the kick panel. The wires look good, no scraping, no pinched wires. So I was a bit puzzled.

    I look at the back of the door panel and saw what I thought to be coffee stains, uhmmm, maybe the previous owner spilled coffee... voila.. that it was. I removed the door module and saw remnants of coffee stains on the plastic.

    I decided to take to take apart the electronics off the inside of the module. I took a q-tip and some alcohol and rubbed it all over the green circuit board, although it didnt appear to be dirty to the naked eye, the q-tips where black.

    Now everything works poifect. I bet some coffee or water got in there at some point.

    Just thought to put it out there for anyone else that has the same problem.

    Thanks to everyone that assisted.

    I wonder how much money the dealer would have charged me?

    Good job! You just saved yourself good amount of money from dealer. Dealer could've replaced the whole drivers door switch module plus diagnostic fee. I'd say maybe $400 to $500 depends on the area and location.

    Not a bit surprised. Guys who run with the window down all the time kills them too.
