Why aren't power windows wired 'always hot' ??

Power seat and remote mirrors are wired 'always hot'. Why aren't power windows wired so there is power to them at all times?
What, non of these marketing/engineer types ever removed the key, started to get out only to discover they forget to roll the windows up??

Now, before someone says that since these are high current devices that could/would draw down a battery or cause the motor to overheat and burnout or cause a fire if any of those switches 'stuck' or shorted out; the same could be said about the power seat (both circuits are on a 25 amp fuse). It wouldn't be hard to design a safety timer circuit where if it senses a 'held' switch for more than x seconds, it would remove power from that circuit.

The only other thing I could think of is some unknown issue with kids in the car, but if you aren't there and neither is the key, why are they?

Enlighten me please.

A lot of the newer cars allow you to roll up the elec windows after the engine is turned off. It is on a timer [1 min?] and if a door is opened before the window is raised [or lowered] the power is cut.

Ok, but how about the ones that don't have this?

Reason why it was done in the first place. Seats, mirrors & door locks are always powered.

It is probably simplier and cheaper to build a car without this feature. I'm sure the main reason it has been incorporated into the newer models is because of the minor aggravation it causes folks like you and me who forget to roll up the windows prior to shutting off the engine. Just another feature that the manufacture hopes will = more sales.

Bottom line - all features in any given car are there because the manufacture believes these features/options will translate to higher profit.

I would think to keep kids from sitting in the car and playing , wearing down the battery , wearing the motors and possibly injuring themselves

Easy solution; a lock out button just as the door locks have.

Anyone else?

I dunno what you're complaining about, my '07 silverado has power to seats at all times, and windows can be rolled up or down as long as you don't open any door after engine shut off, even if you have the key removed from ignition. Same goes for the radio.
If your 2005 chevy has the steering wheels controls , you can customize a lot of these setting such as " lock doors with speed or when out of Park " or
" unlock doors when in Park or when key removed " etc. etc.

All of this is not a problem in my 94 Tercel, I can set in the seat an roll them up and down, rather tough to do them both at the same time. Have a good one. Geo

I figured it was because a coat hanger or other stiff object could roll the window down. Easy access, but the same could be said for power door locks as well.

That being said, I wired the PW in a pontiac to be always on simply by moving a wire in the fuse block. It's neither simpler nor cheaper to build a car this way, it's just the way the fuse block is wired.

A little time with a voltmeter and you too can wire your power windows to be always on.

My 2 cents

I think it might be too easy for a car thief to stick a device into the car and roll down the window and help themself to anything.
My 2000 Taurus has power to windows as long as the door is not opened. The power seat being hot all the time is a good feature because my short wife drives with seat all the way forward and I cant get in with my big belly after she drives so I reach down and move it back about 5 inches.

This car doesn't retain power to the windows or I wouldn't of asked and not all cars do.

This is the base radio. NO steering wheel controls. Actually the radio doesn't even control the chime level!
