Tip of the Month

Fog on the Windows

Windows fogging up in cold damp weather can be a real hazard. There are several things that can cause your windows to fog up, especially this time of year when it’s wet and cold.

First, check and make sure your heater/AC controls are not on “recirculate”. This mode recirculates the moisture in the vehicle but doesn’t get rid of it. Also check the vents in front of the windshield (under the hood) for leaves or debris that holds moisture.
Those old fall leaves can hold a lot of moisture.

Obviously any collection of water in the trunk or floorboards can make this problem worse.

Another thing that can cause heavy moisture and even water on the floorboards is a plugged evaporator drain. The AC system removes moisture from the air when it comes through the evaporator, which is why it is so effective in clearing the windows of moisture. This moisture is supposed to exit the AC system through a small drain under the firewall. If this drain becomes plugged, that water builds up and ends up on the windows.

Make sure the air conditioning is working properly, the dry air it creates will sometimes remove moisture faster than even warm air and can even clear the window before the warm air even comes out of the heater.

Fog on car windows

The last thing to worry about if moisture is persistent, even on warm days is a leaking heater core. This will also cause the coolant level to slowly drop.

Batteries and Cold Weather

Winter is hard on batteries, not only because of the cold but because we often use more accessories on short drives such as lights, heaters, defrosters, wipers and those sometimes equipped and comfortable seat heaters. If you do a lot of short trip driving the charging system doesn't always get time to charge the battery back up after starting.

Alternator output is lower at lower speed driving than when you are out on the highway and with all of these accessories on, alternator output may just be keeping the accessories powered up at lower speeds and not recharging the battery. Each day the battery may become another 1 or 2% discharged leading to a problem within a few of weeks. Running batteries low on charge causes shortened battery life and can cause older batteries to fail.

One way to prevent this is to take the car out once a week for a longer drive, or even use a trickle charger.


If your battery does get discharged due to short trip driving or leaving the lights on it's important to know that it can take 4 - 6 hours to properly charge a good, fully discharged battery. Bad batteries can recharge very quickly has they have very little capacity for storage left.

It is best not to expect the alternator to recharge a completely discharged battery. To begin with, unless you're going on a long trip you won't fully charge the battery, leading to possibly more problems or early battery failure. Also alternators are not designed to recharge a fully discharged battery in good condition. Doing so can overheat the electronic components and shorten its life or cause it to fail.

Automotive Recalls

We often hear about auto recalls when they become big news, but recalls happen quite often and are not always publicized. Many cars running around out on the road have recalls that have never been addressed.

For those who bought used vehicles or have moved since a vehicle purchase, they may not get a notice.

How do you find out if there is a recall on your car? Go to Carfax and enter your make and VIN#. If your car is not listed you can check with a dealer or go to National Highway Traffic Safety Administration or NHTSA.

Millions of drivers could be endangered by operating vehicles that have been recalled but have not been repaired, according to an investigation conducted by Edmunds. They found there were at least 2.7 million vehicles listed for sale last year that still were subject to unfulfilled recalls. There are no laws that require a car's owner to notify a potential buyer that the car being sold is the subject of a recall. More about recalls and 14 of the largest.starbar.gif

Ignoring that Check Engine Light
Check Engine Light When the first GM cars with onboard computers and diagnostic capabilities came out in the early 80's, they could recognize a limited amount of problems and could store less than 20 trouble codes. It's not unusual for an average car today to recognize and set 125 codes or more just for the engine and transmission.

Then there is Anti-lock Brakes, Traction Control, Air Bag, suspension and other systems that have their own codes.

Some of these engine and transmission codes are for problems that usually won't cause problems we notice while driving. We often hear, "that light has been on for years, I don't worry about it anymore" or "Since this is a minor problem, can I continue driving it and not fix it right now?"
Unfortunately you only have one check engine light. If you ignore the light because of a problem that doesn't seem to affect the way the car drives, something else might crop up that will cause big problems and you may not know until it's too late because the light is already on.

Some problems that the light can come on to warn you about can cause poor mileage or be a warning that you may be left by the side of the road soon. Other warnings can be about things that can cause catalytic converter, transmission or engine failure.
