Whenever someone tells me that glucose is the preferred fuel because we burn it first, I tell them that we burn alcohol before anything else. Using that logic, we should all be hocked up on liquor 24/7 . What makes real sense though, is that the body will metabolize the most toxic fuels first.
Some tips on electronics in cold: 1  Most electronic components are not damaged by ânormalâ cold temperatures. 2  Condensation can be a problem, if the temperature cycles between warm and cold with humidity.  Batteries lose capacity in cold (battery powered devices might not work in the cold)
No cold air from the AC system: Usually when a vehicle has a coolant leak on a closed loop system or is running low on refrigerant, the air conditioning system slowly stops blowing cold air into the vehicle. However, when this function stops instantly, it's typically due to a problem with the temperature sensor found in the AC evaporator.
