:thx Hello Everyone, (Love the Internet) with forums like this I can't believe some web pages try to sell help to you. First off like to thank you in advance for sharing your knowledge...
I'll try to keep it most informative yet short as possible.
I did search the first 3 pages of new post of this problem and did'nt find the info I needed. My issue is 2002 envoy sle passenger window wont work by means of master switch and passenger door switch, neither does passenger door mirror and lock. however, after my sweetie had spent almost $2k on dealer control modules both master and passenger to no avail, prior to meeting up with her on the beautifull beaches of florida. I decided to see if with my shade tree mech. skills if I can fix whats already broke, rite...
this is where I am hung up. I can get passenger window up and down by jumping the passenger side window power connector that plugs into the module. as i have mentioned earlier both master and passenger modules have been replaced before. I'm stuck thinking that with key on I can jump the connector yet the module wont do it, got to be module then rite???. Also have check connection at the door hinge, all seems fine. The master switch controls all other windows fine, just not the passenger door and lock and mirror and passenger module doesnt seem to do nothing, not even a little noise. Sorry if I carried on to much, just wanted to give you as much to work with as possible. Thank You all so much.

Oh man! When I read the title, I thought you were talking about your passenger not working (sweetie's side)... I was going to tell you to have her make up for it by keeping her head as far toward the driver's side as possible... I'm not going to go any more graphic than that, but at that point, it's up to you...

Anyway, to the actual problem...

I've had pretty bad luck with GM window switches as the vehicle ages... Having said that, the fact that none of the power stuff in the passenger door works tells you something... I suspect maybe she's got a bad/fatigued power wire somewhere on the passenger side, going to the door...

Find out which pin in the connector is +batter power, and measure it with the key on... If no voltage, try and keep the connectors connected, then jump power to that +B wire in the door connector... If that makes everything work, you've probably got a wiring issue in the vehicle...

Hey Bartonmd, I tried that but you know they dont listen. passenger side,There is a connector that has four wires within it, a hot,ground&blue and orange that plug into the module rite directly below the window switch on the same module. there is power to it and grounded cause I can operate the window by jumping the wires with a (2) paper clips, that reverse polarity thing. but when its pluged into the module window will not work. there are to other connectors plugged into the module, my guess lock and mirror. are you saying a different hot wire could be the culperet. Thanks for the quick reply chief. Tom

hey neighbor :tiphat

i'm thinking that it is a problem with the passenger module. do the dome lights work when you open that door? does the passenger door lock when you press the power locks? the window motor is controlled by a logic circuit that gets inupt from the switch in the passenger door as well as the class2 data bus (from the driver door) so if that logic is fried that may be your issue.

if you're looking for a reasonable replacement, there are two used auto parts stores on starkey road i usually go to

Starkey Auto Parts

Clearwater Automotive

it doesn't matter what color the trim on it is, you can replace it with the trim from your old module

What you're describing here tells me that the passenger side module is probably bad, or at the very least, has a bad ground (if you're testing the motor by grounding to the door, not the ground pin in the connector... If you're grounding to the connector, almost definately a bad module)...

Neighbor Jimmyjam sounds like your in pinellas county also, love it down here.
the only way to lock the door is manually as far as the dome light not sure but i doubt it. but it sounds like you might be on the rite track cause I cant figure out my the master control works fine that is except for the passenger door functions, can you explain more to me on that logical input thingy. Thank you neighbor

well you see instead of having a separate wire going into the door for window up / window down as well as lock/unlock, mirror controls, door switch, etc, there is only one wire going into the door that is a data wire (along with power and ground, of course, and speaker wires i guess). the "door module" (the thing the switch is on that all the wires connect to) decodes the signal on the data bus and does whatever the data bus tells it to do (unlock the door, roll down the window). it also uses that to send data back like when the door is open. the window switch isn't like a light switch in your house that completes a circuit, it is just a signal to the door module to roll down the window. so if the door module fries, most of the functions in your door go away. unless you did something bad and you think you might have severed the data wire going into your door, it is probably just a bad door module. with the rain we get down here, theres a good chance water got in there and cooked it.

I'm up the road in Clearwater, you should come to the meet in october

jimmyjam-thanks for explaining that, I'm with ya now. Qauker steak and lube, rite up the street, well 20 min. anyway. been by there a few times alot of events seem to go on there, never have stopped though. Will have to do it in october, definitley if not fixed by then. I hate to get another module when the dealer replaced both already and still don't work. but what you say makes sense. was thinking of putting a dpdt switch in the console but would much rather do it rite, if I can. The only problem I got with starky's is their prices, know what I mean. sure it's cheaper than a new one though.

if you're in my neighborhood we can swap in my door module and make sure its the module and not the wiring before you drop money on one. they're going for $50 on ebay.

theres a u-pull-it on brian diary, big3 truck salvage
never been there but maybe it'll be cheaper
