    New thread - Electrical issues

    I've since found that none of my driver's door switches work except the driver mirror. Passenger switches also do nothing. Rear switches control the windows as expected. dash dimmer switch doesn't change the brightness. DDM fuse is fine. fuse has been removed from the amp/subs power line so...

    New thread - Electrical issues

    Hey again y'all. I chased a drain in the following thread but it has returned. At this point, I have no power at driver or passenger's door except that I can move the driver's mirror as expected. The speedo and tach are the only gauges that work. Stereo is always active, as long as the battery...

    Looking for feedback direction on Tech 2 clone purchase

    Sure! I'll message you shortly. I also got a lot of documentation from a few guys over at GMTNation when I posted about my Tech2 woes: https://gmtnation.com/forums/threads/tech-2-clone-missing-options.23999/ My next stop is my stabilitrack and disabled TCS. Denali had airbags deleted before I...

    Looking for feedback direction on Tech 2 clone purchase

    I purchased mine for the specific purpose of configuring a new BCM. I took it to dealership to do, as I was told it's something they have to install. Come to find out, it's just for the BCM restraint ID stuff. When I called them back a few months later (I was busy troubleshooting my new...

    Airbag light woes code B1001

    Hey again gang, After my ridiculous seat heater inop/battery drain situation last winter, I have since had an airbag light that was not there previously. I've replaced both sensors with brand new ones and no change. I've also checked the connections under the passenger seat but didn't see...

    2003 Yukon Denali exhaust options

    Dang. I was concerned there'd be too much info and lose track of my point. No one has done exhaust on their gmt800 denali?

    2003 Yukon Denali exhaust options

    I searched and skimmed a few threads but I didn't see what I was looking for so hopefully this isn't a repost and if it is, hopefully someone can send me to the information I need. I'm planning exhaust for my 03 Denali. I have TSP 1 7/8 headers for the truck and an older model pacesetter y-pipe...

    2003 yukon denali electrical woes - sporadic unlock via fob not working, heated seats question

    @BigDogYJ I replaced the seat element in the seat last winter, along with a new seat pad and cover from theseatshop and it resolved the issue. The bottom was definitely shorting out. @slypher25aussie My passenger side would work fine independently, but when I'd turn driver's side on, it'd kick...

    2003 yukon denali electrical woes - sporadic unlock via fob not working, heated seats question

    went and messed with it. the button closest to me lights itself and the other button up and blinks out immediately. The other one lights up itself but clicks off immediately also. The passenger seat can cycle its settings fine but when I hit either button on the driver's side it kicks the...

    2003 yukon denali electrical woes - sporadic unlock via fob not working, heated seats question

    ok, back to being annoyed by this now that we're in sigle-digit weather. I took the control switch completely apart and cleaned it all with compressed air and q tips and such. Got it all cleaned and put back together and same thing. I notice that the passenger seat heater works fine when I...

    *fixed* ANOTHER fuel pump/pressure question 03 Yukon Denali

    I didn't think about using a hose clamp.. Good idea! I was going to burp it again tonight after I got home as well. I did see a puddle under the truck when leaving this morning though, so not sure what that's about yet. I'm hoping it was just runoff from my sloppy radiator swap.

    *fixed* ANOTHER fuel pump/pressure question 03 Yukon Denali

    Yeah, that's what I've been reading! Some folks put a valve in-line, others PLUG their WATERPUMP (tf?). I actually just replaced my radiator this week as the old one was cracked and finally blew out. The innards of the oil cooler portion came out when removing the fittings (my 03's...

    Hello 00 to 06

    I agree with the comments here. It seems these trucks prefer AC Delco parts to Delphi in my (limited) experience with replacing one for the other successfully. As for the harness, make sure you get a new one as well. Even if the old one looks fine, you may very well damage it trying to get it...

    2003 yukon denali electrical woes - sporadic unlock via fob not working, heated seats question

    I don't know if it's weather-related or not, but I've not been having the lock issue the last few weeks.. Also not noticed the security light on the dash.

    09 Tahoe, New fuel pump.. fuel rails dry

    As someone else who came here to chase fuel pressure/pump woes, I'm in a similar boat. Following though.

    2003 yukon denali electrical woes - sporadic unlock via fob not working, heated seats question

    Delayed reaction on my part, sorry. So yeah, it seems the passenger seat heater(s) stay(s) on fine.. until I hit one of the buttons on the driver's controls and when it kicks off, so does the passenger side. I meant to pull the panel this weekend and see what Icould see but I forgot.
