It’s important to check the nooks and crannies inside an engine compartment of a motorized rig to make sure no debris such as leaves, garbage bags or other items are not lodged inside. A small rock chip in a windshield can quickly turn into a very expensive windshield replacement, and front clearance lights are notorious for allowing moisture into the front cap during a driving rain and that moisture travels to various parts of the rig making it difficult to pinpoint a leak inside the unit.
