ismellrealbad Posted February 20, 2003 Report Share Posted February 20, 2003 ...what this black box does? Keyless entry maybe? The reason i ask is because i discovered its playing a part in the reason why my passenger side door lock button does not work (driver side works fine). It has nothing to do with the button or wires because i pulled the button out and cleaned and checked it and its works fine. and i put the driver side button on that connector and it does the same BS. sometimes it will work, but that is only when the box in that picture makes an incredibly loud buzzing sound. its doesnt sound good. then once the door shuts u can only press it once and then from there it will not work again. to get it to work i have to open the door a certain way to make that box make a buzzing sound and then it will work again. then when i shut the door its gone again. WTF?? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 20, 2003 Report Share Posted February 20, 2003 Looks like a keyless entry module to me. Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted February 20, 2003 Report Share Posted February 20, 2003 Hey!!! That looks familar! :shock: That is the Keyless Entry Module... you need that box to complete the circuit of the power door locks. If that box is removed, then the DRIVER'S side power locks don't work. However, the buzzing though is not healthy sounding... it may one of the inductors in the module trying to boost power to make the relay kick and power the locks. Sounds like you need another box... but's that's from first glance. I've got a full three page dignositc flow chart if you need specifics. - RedFox340 Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted February 20, 2003 Author Report Share Posted February 20, 2003 well oddly enough after i snapped that picture today both buttons were unlocking and locking the doors fine at all times and no buzzing was being made. however for future reference since i knew that was going to be a frustrating jinx, i wanted to know. hm i wish i had another box to try out Quote Link to comment Share on other sites More sharing options...
Justin Posted February 21, 2003 Report Share Posted February 21, 2003 You said you need to open your doors a certain way, sounds to me like a worn wire in the flex boot leading to your door. That could cause added resistance, and might be causeing the module to work more than it should, hence the noise? Something to think about.

ismellrealbad Posted February 21, 2003 Author Report Share Posted February 21, 2003 if it acts up again ill give that a look-over Quote Link to comment Share on other sites More sharing options...
eclipse5302 Posted February 21, 2003 Report Share Posted February 21, 2003 Just look on the W-Body page for "repair keyless entry unit". The solider joints inside go bad, mainly because GM doesn't use as much solider as they should on their electronics. Thats why it works sometimes, and not others. You need to take it apart, and resolider the joints inside. The howto page Shawn made will tell you how. No need to replace it, just fix it.

Vegeta Posted February 21, 2003 Report Share Posted February 21, 2003 Are you sure the driver side door wont work if that box is removed? I pulled mine and gave it away since I wont need it. If I have to complete a circuit though I need to know now while the interior is completely apart. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted February 21, 2003 Report Share Posted February 21, 2003 Yes, Redfox is right. The keyless entry module does complete a circuit. There is a TAN-WHT wire connected to one side of the power lock motors. The TAN-WHT wire from the driver side door goes to the keyless entry module. The TAN-WHT wire from the passenger side door goes to the power lock relay. On cars without keyless entry, both TAN-WHT wires are connected together and both are connected to the power lock relay. Completing the circuit is pretty simple. Just take the TAN-WHT wire (pretty fat, 12-14GA) on the driver side and connect it to the TAN-WHT wire on the passenger side. You can find these TAN-WHT wires at the door harness connectors and connect them under the dash, or you can get to the driver side TAN-WHT wire at the keyless entry harness and run a wire up the side to the TAN-WHT wire at the passenger door.

Vegeta Posted February 21, 2003 Report Share Posted February 21, 2003 thank you! I can find tose wires pretty easily and wire them up. Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted February 22, 2003 Report Share Posted February 22, 2003 is it possible that i have keless entry, i have the same box in my car but when i bought the car there was no controler Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 22, 2003 Report Share Posted February 22, 2003 You probably do. Look in the trunk where the antenna is. There should be a single wire w/ a connector on the end coming out of the wire loom. That is the programming wire. Quote Link to comment Share on other sites More sharing options...

chronic139 Posted February 23, 2003 Report Share Posted February 23, 2003 mainly because GM doesn't use as much solider as they should on their electronics. Gm never made that box originally, it was made by TRW. Dont know about new replacements but they are $$$$$$$ big bucks Quote Link to comment Share on other sites More sharing options...
eclipse5302 Posted February 23, 2003 Report Share Posted February 23, 2003 Well, you know what I mean. I know it's made by TRW (as it says on the box), but I like to lump all GM electronics together. There should be more solider on them then there is. With the vibration, and hot/cold temp variations there should be a little more solider. Seems to be the case with a lot of GM electronics...if they don't work some solider joints are bad. But I guess you gotta cut costs somewhere.... Of course, they do hold up well after many years of service, so the general circuit design and component selection is quite good. Replacements are expensive (like anything electronic in GM cars), but with soo many cars having keyless entry and the fact that they can be fixed with about 2 hours total work (including removal/installation) , it's not a huge problem.

ismellrealbad Posted June 26, 2003 Author Report Share Posted June 26, 2003 i solved this problem the other day. i noticed while i was sitting in my own passenger seat if i kicked the carpet in a certain place everytime i kicked it, it would make the buzzing sound. ok so i was like yesssssss found the problem. i lifted the carpet up in that spot and i found this huge connector that was really loose, it was kinda in and kinda out, it didnt want to stay in its place on its own either so i electrical taped that shit together and everything works great now! im so happy to have this stupid little problem fixed. now my passenger side door lock button works too Quote Link to comment Share on other sites More sharing options...
