Is There Any Way To Quiet The Relays On The Curt 4-Way # C56364 For a 2017 Buick Envision?

Question:

2017 Buick Envision Essence Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector Item C56364 Are there any silent relays for the Curt wiring harness? They are noticeably loud inside the vehicle. We keep them out and only put them in if/when towing a trailer, which works well. Just curious if there are any relays that dont make an audible click when braking or using the turn signal. Thank you.

I recommend covering the relays on the Curt T-Connector Vehicle Wiring Harness # C56364 with a thin foam or HushMat type product. I could not find any relays which are silent or quieter than the relays you have. That does seem like a poor placement from Buick to have that vent panel and no cover on the fuse panel inside the vent.
