2004 GMC Yukon..battery dead...3weeks worth of parts...

[Big Mama]

Glad to hear you’ve narrowed it down Jo. I’ll be interested to know how it turns out and how this all started like if there are any early warnings etc. Be well

Hello,

Thank you for this forum. Looks like many others have also had dead battery issues. Which just suck!

I have darn near tried all the tricks, and need a fresh pair of eyes...and brain. Thank you in advance for any suggestions! Here is what I have tried, so far.

Had my cell phone charging, 4th of July, while doing choirs outside. At first, we thought we left one of the doors opened by mistake, jumped the truck, drove around, got home all is well. A few days later, dead battery again. The truck is an 04 GMC Yukon, we bought in 2017. Battery said 04 on it. Changed out the battery...all was well, until a few days later. We also had the "service tire monitor" message. Took the truck down, got 4 new tire monitors, changed out the auxiliary power charger, as that is what my cell was plugged into. AC stopped working on the driver's side, changed out the driver's side HVAC blend actuator. Unplugged alternator, the battery was still charged. Great, we found the problem. Installed a new alternator yesterday...(drove the jeep to work) ..dead battery this afternoon. We have put the voltmeter on it, and nothing seems to stand out as the draw. We actually have 2 voltmeters we are going to double-check everything, right after dinner.
If anyone has any suggestions....it would greatly be appreciated!

This model is NOTED for having problems with the Bose Amplifier which is located in the very bottom of the Console. I chased this problem for a year and finally a speciality radio shop found the problem. They sent out the amp to a shop up north that rebuilds them, tried to rebuild it and wound sending another remanufactured Amp and never had a problem with that. If you disconnect the amp or the radio, the problem will go away, but that's a good test. A reman is about $200 and I'll fairly sure that from your description that this is the problem.

Good luck,

Hello All! @Big Mama @swathdiver I hope this finds you all well!!! What a crazy couple of weeks. Russ is actually a boss for the city, water department...and has been working none stop. We did the process of elimination with the fuses..and are 95% sure it is the dash assembly....causing the parasitic draw. We stumbled across a YouTube.com video about this company https://www.unitedradio.com/automotive-electronics/repair-and-remanufacturing/ face value quote is $175.00 we pay shipping there with a 1-year warranty and return shipping. Our Duramax dash panel will also be shipped to them, as the odometer is English one time and changes to various other languages other times. Then Russ needs a week of vacation to get all of this done! Meanwhile, the scanner 2, got put on hold. We need to add that tool to our collection....but I don't want the responsibility of ordering the wrong one by myself! Thank you very much for all your help this far, I am happy we came across this forum with kind peeps!

Common problem on many GM vehicles. Its called silver migration which is basically corrosion on the circuit board that causes unwanted bridging of trace on the circuit board and they cause shorts to ground and short circuit to circuit which are both very different types of electrical faults but both ultimately drain the battery slowly. Other common faults on C and K chassis that causes parasitic draw is shorted window, power seat motors and shorted seat heaters. Easiest way to troubleshoot a parasitic draw is stick a clamp on DC ammeter on to the battery cable and start pulling fuses for each of the groups I listed until the draw goes away then put the affected fuse back in and start disconnecting loads that the fuse feeds. You will need a wiring diagram to find out what all loads are on any given fuse. Sometimes you can do a quick and dirty on the power seat motors. Just go under each seat and feel each motor. If you find a motor that is rather warm but hasnt been used in awhile, well you found your culprit there. A seat motor shouldnt be warm unless its been used recently.
