Vehicle object-detection sensor assembly
An assembly includes a housing having a chamber. A pressure source is in fluid communication with the chamber. A first sensor window and a second sensor window are each defined by the housing. The housing has a first port and a second port each in fluid communication with the chamber. The first port is adjacent the first sensor window, and the second port is adjacent the second sensor window.
