Review on ACDelco 88983914 Original Equipment Differential by Justin Gerrero

My brake warning light started flashing, as well as the "working brakes" message and a constant ringing. The brake control unit showed no errors. The scanner indicated low brake fluid level, but there is no fluid level sensor. We have determined that the problem lies with the brake diff switch. In my research, all parts sources, including GM, say this part is not compatible with the 2003 Tahoe. This applies to previous models. The only thing I want to sell you is the entire differential valve assembly for $100. This is indeed the right switch for this model. It's exactly the same as the previous models, except the parts suppliers want to sell you a more expensive part. Finding the right key took longer than fixing it. Altogether less than 5 minutes passed without chaos.
