Is A/C Harder On My Engine?

Ken,

I’ve heard from several people that running the air conditioning is bad for the engine.  Is this true?  Why would it hurt the engine?

-Jeff D., NV

Jeff,

This bit of misinformation has been around for years.  In reality, running the A/C shouldn’t have any effect on your engine.  Your engine has to run anyway while you’re driving, it might as well use some of the power it creates to make your air conditioning work.

Cars are definitely built with A/C in mind, especially nowadays.  If cars were really damaged by running the A/C, there’d be a lot more cars in the junkyard.

Why Did My Power Window Stop Working?

Ken,

My passenger side window just gave out.  Now it’s stuck in the down position, and I need to drive an hour to and from work.  What do I need to replace to get this fixed?

-Mary D., VT

Mary,

When a power window fails, it’s usually either the switch of the window motor.  To test, the easiest thing to do is check the motor.  Take a voltmeter and test the positive and negative connections.  If they get power (usually 12 Volt) when you flick the switch, you know the switch is good and the motor is bad.  If they don’t get power, the switch is bad and the motor is probably good.

To fix the situation, contact your dealer about replacement parts, or order them online if you can.  replacing the bad part should make everything work.

Why Did Both My Windows Stop Working?

Ken,

Both the driver and passenger power windows suddenly stopped working this morning.  I’ve checked the fuses and nothing seems to be blown.

- Jordan H., IL

Jordan,

If you’re certain that the fuse controlling the windows is still working, the problem is almost certainly with the window relay switch.  Depending on your car, this switch might be located in the driver’s side door, behind the dash, or under the hood.  Check your car’s manual to find the location of the switch and make sure it’s getting power.  Also check the connections from the relay switch to the power window motors.  If the relay is getting power, but the motors are not, then you’re looking at replacing your relay switch.  These units are typically pretty cheap, so thankfully you’re not going to break the bank.

How Can I Add More Power to My Car?

Dear Ken, after buying a great used car on Cars for a Grand have I’m wondering what can I do to get more horsepower besides adding a supercharger or turbo.

I am looking to get all the horse power I can without buying a supercharger or turbo.

Thanks.

- Rick M., NH

Dear Rick, these days there are several ways to add horsepower and torque. These range from simple, inexpensive after-market changes and bolt-ons to more complex and very costly modifications.

Check with a local speed shop that you trust.

Hope this helps.
