Critters in the Engine?

Inspecting for Rodent Damage After Winter Storage

As the Adirondacks finally begin to warm up in April, many Boonville drivers are bringing their seasonal vehicles out of storage or simply giving their daily drivers a thorough spring check. One of the most common and frustrating problems we see this time of year has nothing to do with mechanical wear and everything to do with local wildlife.

The Winter Nesting Problem

During the deep freeze of winter, mice, squirrels, and other rodents often seek shelter in the warm, protected spaces of a vehicle’s engine bay. Modern cars are particularly vulnerable because many manufacturers now use soy-based insulation on wiring harnesses. To a hungry rodent, your car’s wiring looks like a buffet.

They can chew through critical electrical lines in a single night, leading to a host of “ghost” problems like:

• Flickering lights or dead electronics
• Engines that refuse to start
• Mysterious check engine lights
• Clogged HVAC ducts and intake systems (from nesting materials)

The Pre-Drive Inspection: What to Look For

Before you head out for your first spring drive, perform a quick visual inspection under the hood. Look for tell-tale signs like droppings, chewed plastic, or piles of acorns and nesting material.

Pay close attention to the wiring near the battery and the firewall. Safety Note: If you see exposed copper or frayed insulation, do not attempt to start the engine, as a short circuit could lead to an electrical fire.
