Part was put in at the end of October and has been working flawlessly ever since. Didn't have to splice anything. All factory harness connection.

Update: I disconnected the rear hvac control module (linked above) which SHOULD have turned off the blower (if it was faulty) and the blower still kept blowing. Only after physically disconnecting the harness going to the blower was I able to get it to turn off. This tells me there's potentially a relay that's stuck closed. Anybody have any idea what relay controls the rear blower and where that fuse box is?

Having some strange issues with the 03 GMC Yukon SLT of mine. Last couple of days the wife tells me it's showing a "battery not charging" error on the dash. Charged it up last night when she got home from work, and had to run some errands today. About the first 10 minutes of driving around the error would display intermittently, until finally it quit, and the gauge was showing a constant 14V to the battery. Had the guy at O'Reilly test the battery. Tested good. He tested with and without the engine running, both tests showed good, so the alternator, at least for the time being, should be good. Then, on the way home from our errands, the rear HVAC blower kicked on, even though the dials are all set to off. Tried move the dials around, nothing. Even with the engine off, key out, and driver and passenger doors open, the rear hvac blower was on. Disconnected the battery about a half hour. Came back out, and as soon as I made the connection (which sparked, telling me there's a current draw) the rear hvac kicked back on. The HVAC issue may or may not be connected do the battery charging issue. I DID recently replace the rear hvac control module ( https://www.ebay.com/itm/03-06-Yukon-Denali-Escalade-Suburban-Tahoe-HVAC-Rear-Control-Module-15185966/133553680962?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 ). Anybody have any ideas? I've read some forums about pulling fuses "under the seat" but have no idea what they're talking about. I only know of 2 fuse locations, one under the hood, and one on the driver side panel of the dash.
