Will a bad clutch fan affect your air conditioning?
Definitely, a bad fan can damage your vehicle's air conditioning system. This is what normally acts as a heat exchanger for the air conditioning unit. The fan is designed in such a way that it helps in keeping the condenser cool, by which that component can convert the gas into liquid efficiently and can keep the convertible's AC system operating smoothly. Thus, when the fan becomes defective, it creates various complications in the AC unit. Lukewarm air, burning smell, overheating while idling- are the symptoms of a bad clutch fan. The car owner should an accomplished car specialist right away to restore the performance of his vehicle's air conditioning system.
1999 Cadillac deville blower motor wont work?
Looks like you have a bad ground or the controller has blown. Remove the motor and connect it directly to the battery to make sure it works. Remove the controller and connect it directly to the fan and battery and check it. Check all the fuses in the car and replace bad ones. Get a light tester or a multimeter and check for power and ground at the motor connection with the fan activated and work down circuit if you are not having power or ground Could be a relay/switch or a loose ground. It would be very helpful if you can have access to a diagram. This video on Youtube is very helpful to your problem. http://www.youtube.com/watch?v=TFD8ZqXuj... Good luck.
Why does high coolant temperature affect the cooling of the air conditioner in a car?
The answers I've read here missed a point I'd like to add.First, modern A/C loops are not usually affected by engine coolant temp, as the AC condenser is always in front of the radiator (or possibly next to it).However, two things can affect AC performance based on the engine getting over hot.AC cutoff - in times of extreme engine cooling demand, the engine can cut off the AC compressor to save that heat load on the radiator. A brand new vehicle will usually be designed so that never ever happens, but a few years of wear and tear on all the cooling components can reduce their effectiveness and make this happen.Other Thermal loads. If an oil cooler or charge air cooler is in front of the condenser, their increased load could reduce AC performance.As everyone has said, typically engine cooling is difficult at speeds that provide plenty of air for the condenser. And typically idle, which is difficult for the condenser, is nothing for the engine cooling circuit.If your AC is cutting out during a strenuous drive, my guess is your condenser or radiator is fouled/corroded enough to reduce its performance enough to kick in the cutoff feature.
Why does my car's temperature get high when I turn the AC on?
Assuming that the auxiliary fan (s) come on when the A/C is on, There are several reasons that the temp gauge rises….Is your temp gauge accurate? Most car companies have the dash gauge designed to go to the middle of it’s sweep and stay there, unless the engine gets really hot, they usually just goes to the middle and sits there, as long as the coolant temperature is between 70 C and 100C. They make them like that so that the consumer doesn’t see it moving around on a regular basis, that way, when it does go up, it gets noticed quicker. To determine if yours is accurate, or if it’s the kind that just sits there until something goes really wrong, an OBD2 code reader talks to the temp sensor that the engine’s ECU ( Engine Control Unit )… If the reader shows the temperature rising, but the dash gauge doesn’t budge.. then you know..Let’s assume that your gauge IS accurate… When you turn on the A/C , several factors now come into play. First, you’ve just placed a ( slightly) higher load on the engine, which is now burning more fuel, and creating a bit more heat. Secondly, that fan that just started spinning? Yup, it’s electrically powered, which means the Alternator is now needing more power from the engine.. A bit more fuel, a bit more heat created for the engine’s cooling system. Thirdly, all that energy ( Heat ), that the A/C has removed from the car’s interior .. Guess where it’s going?.. To it’s own little radiator, properly called a condenser coil, and that’s located right in front of the radiator. So now you have hotter air than before passing through the car’s radiator.Thermostats don’t “pop” open and closed, they open a bit as the coolant temperature gets to the design spec of the cooling system. They don’t open to full flow for at least another 10 C.Thermal efficiency.. As a radiator gets older, scale buildup on the inside of the tubes inhibits the transfer of heat to the air passing over the fins.Add all these together, and you have the reason that the temp gauge moves when you turn on the A/C..
What are common causes of water leaking from under a car?
That depends on the quantity of water.It can only come from three places. The cooling system, or the windscreen washer system, or the exhaust.I'm pretty sure you can ignore the washer system.The exhaust will push out a small quantity of water as a natural result of the combustion of the fuel. It is obvious and will be evident as a small wet patch under the tail pipeI'm pretty sure you can ignore that too.If there is more than a very small puddle you probably have a coolant leak.Although why you should find the leak under your car at whatever moment you found it is a bit of a mystery. Unless it started just after you parked, purely by coincidence.If you have over heated the motor it will cause the water in the cooling system to steam. This will cause a small puddle.The fact that it has over heated is cause for investigation.The other reason might be that there was too much water in the system and it overflowed as a result.Water expands as it gets hotter. There is often a header tank that is designed to accommodate the extra volume of hot water. By filling the header tank over it's maximum while the car is cool, you over fill it. When the car reaches operating temperature the water will overflow through the overflow hose.
What are some symptoms of a bad idle air control sensor?
Idle air control valves open to allow more air to "leak" into the intake, raising the engine rpms, or close when not needed. When your AC compressor kicks in or power steering is activated as you suddenly turn the steering wheel, the sudden drag on the drive belt will bog down the engine. These systems send a signal to the engine computer telling it they are active and it then signals the IAC valve to open, which increases the engine speed. Without this occurring, the engine could struggle, or die. The IAC valve can cause weird idle issues, mess with throttle functionality or cause the car to die. Sometimes they fail, get stuck or just get all carboned up. Sometimes people have success at cleaning them, but generally it is best to replace them when bad. Idle issues and even problems with the IAC valve may not be due to the IAC valve being bad itself. An idle issue does not mean the IAC valve is bad. It is best to pay close attention to how the vehicle is acting, and then communicate that clearly and as completely as possible to your mechanic. Intermittent problems can be very hard to diagnose. Details will help. Knowing more about the vehicle in question and its symptoms (in detail) will also help in understanding more about what it is doing.
Why does the steering wheel lock up while driving?
What Causes the Steering Wheel to Lock Up? | eHow Losing control of your car's steering is a terrifying experience, one that can lead to a crash with horrific consequences. If this happens to you, then you must try to bring your vehicle to a stop at once and determine the cause of steering wheel lock-up before you drive your car again. There are a number of reasons why your car's steering has suddenly locked up including:Key MechanismNot every steering wheel problem occurs when you have the transmission engaged and are heading down the road. Sometimes, drivers report that their steering wheel stays locked even after inserting the key into the ignition. When that happens, the car probably cannot be started let alone driven. More than likely the key assembly has worn out and needs to be replaced. However, before calling your auto mechanic, try to move the wheels to the left and to the right as sometimes the steering column "catches," a problem that can be resolved if you jiggle the wheel.Lock PinGeneral Motors issued a pair of recalls for the C5 Chevrolet Corvette (1997-2004 models) due to problems with locked steering. In addition to being locked while starting, owners complained that in some cases their cars could be driven but with no control of steering. This problem is due to a lock pin that fails to withdraw fully, allowing contact between the pin and lock plate. Visit the National Highway Traffic Safety Administration (NHTSA ) website (see Resources) for information about recalls #04006B and #04006C or call your Chevrolet dealer.ConclusionWhile the three causes mentioned here are among the top reasons why a steering wheel may lock up, there could be other reasons. Contact an auto mechanic for assistance, or if you are handy with repairs, consult a Haynes or Chilton repair manual (or anything similar) for guidance.
