MICE CHEWED YOUR CAR WIRING? A PUEBLO REPAIR GUIDE
Every year we see the same thing at our shop on N Erie Ave: a car that ran fine last month suddenly won't start, throws a strange code, or smells like something died in the vents. Pop the hood and there it is — insulation shredded into a nest, seeds in the airbox, and copper showing through a chewed harness.
Rodent damage is one of the more common electrical problems in auto repair around Pueblo, and it's one of the most misdiagnosed.
Why It Happens Here
Mice and packrats want somewhere warm and dry, and an engine bay is exactly that. Cars parked near fields, alleys, garages, or under trees are the usual targets, and vehicles that sit more than a few days are far more likely to get hit than daily drivers. It doesn't matter how new the car is.
Signs to Watch For
- Check-engine light with codes that don't match any symptom you're feeling
- Crank but no start, or intermittent no-start
- Blower motor, headlights, or a single accessory that stopped working
- A rodent or musty smell through the vents
- Nesting material or droppings on top of the engine or in the air filter box
- Chewed rubber lines or exposed wire when you look closely
What the Repair Involves
Honest answer: it depends on what they got to. A single chewed wire on an accessible harness is a fairly quick repair. Damage buried in a main engine harness, or several wires cut in different spots, takes real diagnostic time to trace circuit by circuit.
That's the part most shops don't want. It's slow work, and there's no shortcut — you follow the wire until you find the break. We'd rather do it right than sell you a harness you may not need.
Insurance Often Covers It
Rodent damage usually falls under comprehensive coverage, not collision. If you carry comprehensive, call your agent before you pay out of pocket. We can document the damage for the claim.
Keeping Them Out
Park in a garage when you can. Don't store pet food or birdseed near where you park. Pop the hood every couple weeks on a car that sits. Peppermint oil and ultrasonic devices get mixed results — physical deterrence works better.
