What did you do to your NNBS GMT900 Tahoe/Yukon Today?

So I'm looking for replacement junction fuse blocks for the tahoe, I bought one from the wrecking yard that came off a 2008 LT Tahoe- its got a sticker on it that says "SX" whereas the one off mine has a sticker that says "UT" and there are some pins on the bottom that are different. Mine has a few extra ones in some places and the parts yard one has a couple that are missing. I'm reading on GM Parts Direct that the actual part number is compatible with all LS/LT/LTZ trim levels? What gives? I have all the fuses pulled out and the panel is sitting in the oven set to 190* drying out.

my first guess would be the sticker just indicates what plant it came from, the pins present or missing are probably indicative of what the trim level was on the vehicle it was removed from

I don't think the wiper circuit should be pulling 25 amps. Yes, your fuse block may be bad, but it could've been damaged from the motor drawing too many amps. It's worth investigating to ensure you don't burn up the replacement fuse block.

Part number on old block is 15092625 and part number on the one i pulled from yard is 25815387. The lady at another yard I went to said 07-09 interchange, and the 5.3 vs the 6.2 also interchange but who knows if shes correct or not.

This listing makes me think they do interchange? https://www.justparts.com/Auto_Parts/GM-OEM-Fuse-Relay-Junction-Block-19210438/26210732

It was blowing fuses because I only had like 1/16 of an inch exposed on the purple wire and no way to maintain a solid connection.

according to that link then these should crossover: 19210438, 19210440, 25796803, 15910897, 25815387, 25815389

Who needs wipers anyway? Remove the arms and the motor and free up some weight and reduce wind resistance!!
