What's your comfort zone?

As car owners, we push a few buttons or turn some knobs, and voila, we have warm air blowing on our feet or cool air chilling our face. How does all that happen? Well, it’s all thanks to the air blend box. This box lives behind the dash and conveys just the right temperature of air right where it is wanted.

Let’s break it down. First there is the blower fan that circulates the air through the heating/air conditioning system. The fan can blow at different speeds, depending on how much hot or cold air is required to be comfortable. The blend box can either deliver fresh air from outside, or recirculate air from inside the cabin. Saskatoon auto owners often choose to recirculate air when first starting the vehicle until it starts to either cool down or warm up. In recent weeks it was recommended to only recirculate air in the vehicles due to the forest fires and the high air quality health index.

The next thing the blend box does is convey airflow over the heater core to warm the air, or over the air conditioner evaporator core to chill it – it can also blend both hot and cold to get it just right. From there the blend box can direct the air out into the passenger compartment through the floor vents, the panel vents, the defroster, or a combination. All of this allows drivers to customize the climate just the way the like it.

Some vehicles have different climate control zones, like one for the driver and one for the passenger – or even more zones for the back seat. Additional blend boxes are used for this. Climate controls could be manually adjusted or computer controlled depending on your vehicle.

The blower motor and all of the little actuator motors that open and close the various blend doors can fail and need to be replaced. Most new vehicles come with a cabin air filter. This filter cleans the air before it gets into the blend box. If you neglect changing the cabin air filter, it can get clogged, smelly, and even allow mildew and other microorganisms to build up in the blend box.

At Crestview Auto Service, we can carry out a heating/air conditioning system-cleaning service that will clean and disinfect the system, restoring a fresh clean scent. If you are not getting enough hot or cold air, let us inspect your system, diagnose the cause and set things right. Also, don’t forget to replace the cabin air filter on schedule. Keep in mind; if you live and drive in dusty conditions or where there is a lot of pollen or other pollutants, you may need to replace your cabin air filter more frequently. We are here for you.

Winter Driving in Saskatchewan

How well did you prepare your vehicle for winter? Here are some things to remember and some tips to help ready yourself for a winter trip. Plan to be safe this winter when you are out on the road, reducing the stress of winter driving.

Have your vehicle inspected and serviced to be sure you won’t break down in the cold. Winter conditions with snow, cold and icy roads demand that a vehicle be in top condition. For this reason, a winter readiness inspection is a necessity, and in the end is less annoying and less costly than battery boosts, calling a tow truck, being late and those unplanned hotel stays half way to your destination.

Before it’s too late and you’re on the side of the road or worse, stopped in the middle of the road, give us a call, e-mail or book online to set up an appointment for your vehicle. You will know the condition of your vehicle and what needs to be done for safe winter driving.

Having a block heater on your car and using it when temperatures are colder than -15⁰c is the least expensive way to prevent engine damage from cold winter starts; just make sure you unplug before driving away.

Remember; daytime running lights on your vehicle usually only have the headlights on, not the park lights. They provide less light than when you turn the lights on yourself. At dusk or inclement weather you need to turn the lights on manually so others can see you from the front and the back; swirling snow, fog and cloudy days make it difficult to see and to be seen.

Tips before you head out on the road each day:

·        Unplug the car

·        Brush the snow off your car.

·        Scrape the windshield, rear and side windows.

·        Clear your heater air intake (this is usually between the windshield and the hood).

·        Clean your headlights, tail lights and signal lights.

·        Be sure to clear your tissue boxes, sunglasses, papers, etc., away from defroster                  outlets or your windows won’t clear properly.

Winter and Tire Differences

Often at this time of year we are asked “why isn’t an all season tire or even a four-season tire [with the snowflake symbol on the tire] good enough for winter?” The difference is in the type of rubber and the design of the tread. The most common comment we hear from someone after having winter tires is “why did I wait so long to get them?”

All season tires are really only 3 season tires at best. The tread is designed for long life; because of this the tire does not have the lugs needed for good snow traction. Also the rubber used in the tread becomes hard and less flexible as the temperature starts dropping below 7 degrees Celsius, making the tire slip on ice and snow.  

Four season tires are a compromise and winter traction is sacrificed to get longer life out of the tire. They are really all season tires with a slightly more flexible rubber compound and a tread pattern that works ok in snow. Unfortunately, the tread compound is designed for long life making it only a bit better than all season tires on ice.

Winter stud-less tires are the best for most winter driving; they will have a very flexible tread that grabs the road for the best traction through the winter. Some winter tires have provisions for studs. These tires generally have a blockier tread pattern that is great in snow but the tire does not flex as much as a stud-less winter tire; these tires rely more on the studs for the added ice traction.  

At Crestview Auto Service, we can help you find the winter tire that is right for you. We recommend booking in late September/early October. Remember to book ahead of time. Appointments can be made online at www.crestviewautoservice.caor by phone (306) 244-6522. We look forward to helping you be prepared for winter driving.
