Niagara Gazette — Transmission and differential damage from snowplowing — passenger rated vehicles are not made to plow snow, period. Transmissions, differentials, axles and CV/Universal joints break under this abuse. Only heavy-duty vehicles are built to withstand the rigors of snowplowing. Recently I heard of a man who installed a plow on his new light duty pickup. While plowing he hit an ice-packed snow bank, not only did he damage the drivetrain, the air bags blew! He was saddled with the repair bill on his brand new truck with no warranty! Why? Because the vehicle was not rated to plow snow.
When its cold, a car battery that is in marginal condition will fail. It is the combination of the cold, increased electrical load from running heaters on high, wipers going, lights, starter draw and a weak battery that breaks the back of a marginal battery. Not to mention a loose or worn serpentine belt causing the alternator to slip and not properly recharge the battery. The best thing you can do is just prior to winter setting in, have the starting/charging system check along with a battery load test. Tend to anything that’s marginal and you’ll be good-to-go.
Doors and glass — After parking a warmed vehicle, ice and snow light on the door glass. When the precipitation hits the glass, it melts and runs down to the base. There’s a squeegee gasket made of rubber designed to stop water from going down inside the door. If this gasket is worn or maladjusted, water gets inside the door and soaks the door linkage, lock mechanisms, and window regulator, this freezes the lock and window mechanisms. The next time you try to enter your vehicle the locks are frozen, so you force the lock or door handle to get inside the vehicle. Suddenly something pops and the latch feels sloppy. You have just broken a linkage or latch assembly. The door has to come apart and the lock and/or latch repaired or replaced.
