Mike7143 Posted February 14, 2023 Share Posted February 14, 2023 (edited) Somebody broke the driver's side mirror off backing out of the garage. Drove around a few day with a crafty duct tape job, no issues with BLIS or Cross Traffic systems prior to the event or for those few days. Ordered and installed a replacement mirror assembly from an aftermarket manufacturer (TRQ) that's got power, heat, puddle light, and 1-piece with blind spot. Now whenever I shift out of park I get "BLIND SPOT SYSTEM FAULT" and "CROSS TRAFFIC SYSTEM FAULT" in the dash and chimes. Disconnected the new mirror, plugged in the broken mirror, no issues. Plug new mirror back in, faults come back when shifting from park. From what I can tell by taking apart the broken mirror assembly, the BLIS indicator is just a LED on a little board with some surface mount resistors. The actual sensor is in the rear I presume, in the rear bumper cover. Doing my A-B-A swap would indicate the issue is clearly the new mirror. Question is, do I mess with a replacement and maybe mine is defective or should I just go with a refund and find a used OEM part because there's something odd with the BLIS indicator these aftermarket guys can't figure out? Certainly the LED indicator isn't somehow needing "programmed" or something? Edited February 14, 2023 by Mike7143 0 Quote Link to comment Share on other sites More sharing options...

Let us know how you make out and good luck. 1 Quote Link to comment Share on other sites More sharing options...
