Vent windows are gone – have your AC checked before this McHenry summer arrives in full force

Vent windows once gave drivers and passengers in

some air on hot days. Cars generally don't have vent

windows anymore now that almost all vehicles have

AC. With summer approaching, it's time to have your

AC checked.

You just don’t see many vent windows in the vehicles around McHenry anymore. That’s because air conditioning is standard equipment in virtually every vehicle sold today. Vent windows were made to scoop some air into the vehicle while you drive.

Think about a driver pulling out on the road on a really hot day in McHenry 60 years ago. Their car doesn’t have air conditioning. No doubt, they’ll roll the windows down. But as their vehicle slips through the air, only so much air will come into the car. This is where vent windows came in.

Vent windows were mounted at the front of windows for the driver and passenger in the front seat. They had a manual lock that pivoted down to hold them in place. Flipping the lock up, the vent windows then tipped out so they caught the air and directed it into the vehicle.

On a hot day, this gave people in the car a blast of air that, hopefully, had a cooling effect on the driver and passengers. Of course, if the temperature was too hot that day, it might have been a blast of hot air, in which case they would close the vent windows.

Another potential drawback to vent windows is that the blast of air was akin to having the top down on a convertible. If someone has a nice hairdo, it might be a little mussy by the time you get where you’re going.

As the popularity of air conditioning increased, the demand for vent windows dropped. They kept dropping until, as is the case today, you hardly see any vent windows on any vehicles.

With air conditioning, you simply roll up the windows and turn the air on. Then you adjust it to the temperature you want with the fan at the level you desire.

The drawback with air conditioning is when the AC fails or if it just isn’t quite up to the job. As summer approaches, this is the right time to make sure your car’s air conditioning will do the job. Remember, you don’t have vent windows to help on a hot day.

It’s possible the air conditioning is low on its charge; you simply need a qualified auto repair technician to recharge the system.

At other times, a compressor, condenser or another essential part will fail. You may find that your AC blows nothing but hot air into the car.

Summer is coming to McHenry. This is a great time to have your AC checked, even if you have an older car with vent windows.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
