Rear Window?Not the Movie! (Why Some Rear Windows Don't Go All the Way Down)

Alfred Hitchcock once made a mystery thriller film called "Rear Window." It had nothing to do with the rear window of today's cars, SUVs, CUVs and light trucks.  But there is one thing that some drivers DO find mysterious.  Why don't the rear windows in the second row of many of these vehicles go down all the way?

You've probably seen or owned one or two. That rear side window only goes down about a third, a half or three-quarters of the way. Yet there are some similar vehicles where the window goes down all the way.  What gives?

There was the rumor going around that the restriction on how far those windows could go down was a child safety feature.  The thought was that if those windows couldn't open up fully, a child (or pet) would be less likely to fall out.  But it turns out the real reason is that the way the rear doors were designed, there was just no room for the window to go down all the way into.

Many vehicles are configured so that the rear wheel arch continues into the rear door.  That arch restricts the space that would accommodate the window, so they had to stop the window somewhere higher than bottom of the door.

Seems buyers would prefer those back windows to go all the way down, so many manufacturers are changing designs to make that happen.  Longer vehicles can have their wheels pushed further back so the wheel arch isn't an issue.  Some have altered the position of the rear window track. 

If you have any questions about your rear side windows, you may want to consult your service advisor to check yours.  If they ARE supposed to go all the way down and they're not, it could be due to a few problems: corrosion, broken or bent window regulator components, electrical issues, etc. But if they're not supposed to go down all the way?  At least now you know for sure.

Keeping Your Cool (Water Pump Replacement)

No matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected.  Well, cool, anyway. If your vehicle has a gasoline engine, it's powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT.

There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump.  Technically, it's pumping more than water. It should actually be called the "coolant" pump since the liquid that circulates through the system is a mixture of water and coolant. 

Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that shows the temperature is too high, it could mean a bad water pump. 

They can fail for many reasons. They have bearings in them that wear out, as does the seal between the pump and the engine. They're often driven by a belt or chain that can go bad.  Corrosion can spell the end of a water pump, too. 

If a technician determines your water pump has failed, it's time to replace it. In addition, other components of the cooling system will be inspected.  The best way to avoid a water pump failure is regular maintenance of your cooling system which includes regular draining and flushing of the coolant. 

Just like it's important for you to keep your cool, the same goes for your vehicle's engine.
