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.

Auto Maintenance Basics: Anti-Lock Brakes



There’s a common misconception among Saskatoon drivers that Anti-Lock Brakes help you stop faster. That is not always the case on loose gravel, wet roads or snowy surfaces. Anti-Lock Brakes, in fact, are designed to help you maintain control of your vehicle in an emergency braking situation.

Imagine you are driving on a wet Saskatoon road. You need to slam on your brakes and your rear wheels lock up. Chances are good that the rear end of your vehicle will try to pass the front end and you can easily lose control. What would happen in the same circumstance if your front wheels locked up? Well you certainly would not be able to steer properly and your front end would go to wherever gravity leads it. The Anti-Lock Brake System (ABS) modulates your brakes on and off as many as 15 times a second. This keeps your wheels from locking up while providing the greatest amount of braking possible. You are better able to steer your vehicle and maintain control. Saskatoon motorists often talk about the 3 S’s of Anti-Lock Brakes: Stomp – Stay – Steer. Stomp on the brake, Stay on the brake, and Steer normally.

Modern ABS utilizes a computer to receive information from sensors and control the anti-lock brakes. There are wheel speed sensors at each wheel reporting back to the computer which can then decide when to activate the anti-lock brakes on the wheel or wheels in need.

So what affects how well the ABS works? First, the condition of your brakes: If you brakes are worn or not working properly, the ABS will not be able to do its job as effectively. A brake inspection at Crestview Auto Service in Saskatoon will let you know if your brake shoes/ pads are in good condition, if there are any mechanical brake issues and if your brake fluid and power brake system is in need of service. Proper brake fluid maintenance helps keep the brake control module in good working order. There can also be problems with the various sensors and the wiring that sends the messages to and from the computer. And of course, your tires need to be in good condition in order to have enough traction to start, stop, and steer. Worn tires are a big problem for ABS and Stability Control Systems.

The ABS is the foundation of Stability Control Systems, providing the vital information needed for stability control as well as to strategically brake a wheel when needed, so making sure your ABS is working well is very important. Also, the rolling diameter of your tires is one of the factors on which the computer uses to base anti-lock decisions. If you buy tires that are more than 3% larger or smaller than the tires that were installed at the factory, the ABS and Stability Control systems will not work properly. The computer can be recalibrated for the new tire size so that the systems have the correct information.

When you start your vehicle, the ABS light will briefly illuminate on the dashboard. If the system detects a problem with itself, the light will stay on. That is your cue to bring your vehicle in for an inspection to determine the problem. Crestview Auto Service is your partner in keeping this important safety system operating as it should.

Why do wheels need to be re-torqued?


Re-torquing wheels after vehicle servicing

When you bring your vehicle to our repair shop, if we have had your wheels off of the vehicle, we will ask you to return so we can re-torque the wheels. Your invoice will also have a statement on it advising that the wheels need to be re-torqued. You can do this yourself if you like, but if we were the ones to work on the car we do this at no charge to you. We always use a torque wrench to tighten your wheels when we re-install them. This is more of a safety concern now than it was 20 years ago. Vehicles are much more reliable today, but they are made with lighter materials and some of these are very fussy about how they are put together. Even a slight decrease or increase in the tightness of bolts and nuts can have adverse affects, in that they can loosen or they can break. 

Occasionally a customer will come into our auto repair shop with a concern of a noise; once in a while we find loose lug nuts that hold the tires and rims tight to the car. This usually happens shortly after they have had the vehicle in for servicing somewhere and the wheels were off or they have taken the wheel off themselves. Most automotive shops will use a torque wrench to tighten the wheel and this is the best way to make sure the nuts are tight but not so tight that the wheel studs break from too much pressure on them. Some vehicles are more prone to having the lug nuts loosen and will need multiple re-torquing to make sure they stay tight.

Loose wheels don’t happen often, but to be safe, have your wheels re-torqued within the first 100 KM after they have been put on. It is the responsibility of the vehicle owner/driver that this is done. Loose wheels can cause a lot of damage to your car and potential injury to you and others. It doesn't take long to re-torque wheels and could save you a repair bill and a big headache.
