Every time I turn on the AC, my engine dies. Why is this?
Cars are complex so not easily diagnosed on line. I can offer an idea or two.AC puts an additional, heavy load on the engine.. Nature of the beast.SoEither your Engine is running badly, barely producing power to sustain itself.The additional load is breaking the camals back - so to speakOr your AC is overcharged with gas imparting a burden / power demand on the engine beyond its design parameters. NOTE. Modern cars have AC gas pressure sensors that will stop this problem before it occurs.Once again, too many variables to give a straight definitive answer.
Do I need to replace the Blower Motor?
I have a 2002 Buick Century. Ever since I've owned it, the Heat and A/C will only blow out if the dial is on 4th or 5th speed. Low - Medium may as well have been an off setting. This morning the Medium high and High quit working too. Now I highly doubt that it's a fuse because then it wouldn't have worked at all. Did I finally burn out the motor from always running it on High? Or do you have another theory of something that may be going on?
How long can a battery last without a functioning alternator?
The answer to this depends on the age of the vehicle. If we are talking about a really old car from about the 1970’s and earlier, you could run the engine for days if you don’t turn on any lights or run the heater or radio, because the only thing other than lights, the cabin blower, or the radio in an old vehicle is the spark ignition, which needs very little energy at all to function.,These early engines used a fan that was direct-driven by the engine, but they would overheat easily if the engine sat idling for long periods, because a slow fan doesn’t move much air through the radiator.Newer vehicles changed from having a cooling fan direct-driven by the engine, to using a separate electric fan with a thermostat that cycles on and off as needed. These can tolerate long periods of idling without overheating, but it increases the load on the electrical system.,There was also a transition from carbureted engines to electronic fuel injection, which added more electric load in newer vehicles. Carbureted engines typically used a simple cam-driven fuel pump that delivered low pressure fuel in surges to fill the carburetor float bowl.But fuel injection requires a constant pressure fuel rail to assure consistent injector results. This is delivered by a fuel pump in the gas tank that runs continuously with the engine running to provide a constant high pressure to the injectors so that they work properly.,Computers in modern vehicles do not use much power by themselves, but they are commonly used to control magnetic solenoids and servos, which may control the engine timing, or change the number of valves that open in cylinders, or change the throttle body shape, or control shifting in electromagnetic clutch packs in an automatic transmission.All of this adds up to increased power consumption in a modern vehicle that will reduce the time a battery can continue to function without the alternator, even if all the marker and headlight lamps are turned off.
What happens when car battery cables are wrongly connected?
Let's say the red cable from the jumper cables is the positive terminal, and the black cable is the negative terminal.The battery with the red cable on the positive terminal will be a +12 V battery, and the battery with a red cable on the negative terminal will be a -12 V battery. When they are connected together, then what you were doing is putting -12 V battery in parallel with a +12 V battery.If you do this, then the positive 12 V battery tries very hard to make the -12 V battery positive, and vice versa. Because a battery is a voltage source, each battery will flow as much current as possible into the other battery trying to equalize their voltage levels.The only resistance to this flow of current is the battery’s internal resistance and the jumper cable resistance. Together, this resistance might only be 0.1 Ohms.Car batteries can easily supply 500 Amps if the load resistance is small enough. So with 24 volts of difference between the 2 batteries, and 0.1 Ohms of resistance, 240 Amps will be flowing between the batteries. The formula for calculating power from current and resistance is P=I^2*R => P=240^2*0.1=5760 Watts of power. Because there is no work being performed, all of that power gets turned into heat.All of that power dissipating as heat will melt the insulators on your jumper cables, and it will melt the plastics of the battery, and it will cause the battery acid in the battery to start boiling.
What is the direction of a radiator fan, suck or blow, in or out?
Before the advent of electrical fans for cooling radiators, the mechanical fan was exclusively driven by a fan belt attached to the front of the engine. This forced the fan to "suck" air through the radiator. This arrangement also looked neater, with the moving parts of the engine hidden from sight. There is an option now for some automobiles, to have the electric fan in the same location, behind the radiator, or in front of the radiator. Once the automobile reaches about 25 mph, the fan is superfluous and in many cars, the clutch fan disengages the fan blade to reduce fuel consumption.
Why do my hazard lights work, but not my turn signals?
Hazard lights and turn signals use the same bulb, so it is not the bulb, the lamp, or the cables to them. Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse.Different vehicles use different circuits, and it is not possible to accurately diagnose the fault with the small amount of information provided. You need a circuit diagram and a voltmeter, and a continuity tester. First locate and test the turn signal fuse. Do you have voltage to and from the turn signal switch?The hazard light switch is not a simple on/off switch. In the “on” position, a fused battery feed connects to left and right turn signal. In the “off” position, the left turn switch wire is connected to the left turn lamp and the right turn switch wire is connected to the right turn lamp, so there are 3 inputs and 2 outputs.The fault could be a fuse, turn signal switch, hazard switch, flasher unit, or a broken wire or connection.
How do you fix a power window that won't go up?
OK, I'm the expert on this one since this is all we do. Specifics are at Power Window Repair Tampa or you are welcome to ask here. In general,If you hear a click as you depress the switch down but no click as you press the switch to go up it might be the actual multi button window switch. Usually if one switch is bad neither switch works.If you hear a click in both directions it might be the window motor. Some can be changed alone, some require you to change the entire assembly (with the regulator). If you want to get the window back up try this. Start the vehicle, open the door, with one finger on the button to put the window up slam the door closed with your other hand. Might get the window working again for a time.If you hear a crunching, grinding sound your regulator (the cables that pull the glass up and down on a metal cross bracket) is usually broken. If you can get the door panel off you can probably push the glass up by hand. If you encounter resistance it is ok to cut the metal cables (never cut an electrical wire) as your get new cables with the new regulator.NEVER try to pull the glass up with a pair of pliers. Glass is pretty strong stuff but much like a diamond can be shattered.To answer your question as to how to repair a specific window would need to know year, make, and model. A youtube search will uncover videos of how to.
What could be the cause of a car’s temperature gauge to fluctuate?
There are several possibilities.1) faulty teperature gauge. In this case the gauage will have to be replaced. This is relarively simple and inexpensive depinding on the make and model of the car.2) Issue with the radiator, coolant of the car. This could be caused due to insufficient coolant, leakage of coolant, damage to the radiator of the car. This will require extensive repair. In this case, it is advised to get the issue diagnosed and fixed at the earliest to avoid engine damage due to over heating.Hope this helps. :)
