Question on the rodant problem is the wiring being chewed a lot less common in the heat of the summer then in the middle of the winter I would think that it would be a lot less in the heat of the summer varmints wouldn’t want to get up in a hot engine but in the winter they do want to nest in the warm engine compartment. just let me know what you guys think?

In general, mice and rats tend to move "inside" during the fall/winter to warmer areas. They are active all year, but the time to be especially vigilant for nesting and chewing is late fall/early winter. Other species such as chipmunks and squirrels use engine compartments and other cozy places in vehicles to store food in the fall and can chew on wires/hoses/plastics in the process. They don't usually nest there, though, like mice do. All species have a tendency for "repeat performances". Once an area in the vehicle has the smell of a nest or a food storage area, there is a strong likelihood of repeat use, even if the original offender is long gone. If you have an infestation, clean, clean, clean.
 
Reading dealership maintenance records can be revealing. I've seen multiple reports of "rodent activity in engine compartment" by dealership technicians servicing TLC's and LX's alike. I've found nesting material in the engine bay of my BMW, and they destroyed the AC wiring harness in my sister-in-law's MBZ. Goes to show the little critters are PC and not racially biased.

When I was having my snorkel installed the tech found an old abandoned mouse nest. That wasn't too bad. During the front bumper install there was a dead bird in the grille!
 
Getting back to the title of this thread: Ya simply GOTTA get rid of these rodents. They are NOT cute! Buy traps & poison. You can get rid of them, but it takes time and a bit of dedication to the effort.
 
A lot of times, you can spray hornet killer in there. The older ones are mint based, and non-electrical conducting. Will "de-grease" marked nesting activity too...
