Steering wheel feels loose and sloppy while driving on a normal road this is because of over-inflated tire or there is a faulty front end component. Reasons why the steering wheel feels loose and sloppy Overinflated Front Tires A steering wheel that feels loose and sloppy while driving is usually caused by front end components that are faulty or sometimes cause of over-inflated front tires. With that said, the first thing to do is check the front tires using a tire pressure gauge, compare the result with the tire pressure recommended by the vehicle manufacturer. If you do not know the value of the recommended tire pressure, look on the tire placard label adhere on the driver side door or look on the owner’s manual included on the vehicle when you first purchase the vehicle. Based on the result of car problem troubleshooting you found out that the problem is the overinflated tire just let loose some air from the tire to make the pressure within the recommended value and correct th...

If air doesn't blow out at all in ac vents at any fan setting, it is a problem of a bower that is not working. Probably the blown fuse or failed blower motor. The reason why Air Not Blowing Out of Vents in Car (1) Car blower not working on all settings because of a blown fuse. (2) Car blower not working on all settings because of a failed motor blower. First off, we need to clear something up. The "blower" and the "fan" are the same things. We used the word "fan" in the problem description because it's a more familiar term. The official name for it (as used by mechanics) is "blower". Now then, it should be obvious that if the air isn't blowing from the vents at any fan/blower setting, the blower must not be working. Two common causes of this are... Blown Fuse - Like most electrical devices, the blower has a fuse as part of its circuit. This fuse can "pop" for one reason or another. This will immediat...

If brake light on the dashboard is on this usually indicates that the brake fluid level is low or, that there's a pressure imbalance in the brake system. However, if the parking brake is inadvertently applied, it'll cause the brake warning light to go on as well. Possible Reason for Brake Light on Dashboard is ON (1) Brake fluid level is low. (2) Pressure imbalance on the brake system. (3) The parking brake is inadvertently applied. If the parking brake was applied slightly or fully, then the parking brake is tripping brake warning light. The parking brake and brake warning light are sort of "tied" together to remind you when the parking brake is on. So, when the parking brake is even the slightest bit applied, the brake warning light comes on. What to do? If brake light on the dashboard suddenly ON, make sure the parking brake is released while driving. If the parking brake is not engaged, Open the hood of the vehicle and locate the brake fluid reservoir...

While driving on flat roads there is a pinging sound coming from the engine, also pinging sound occurs while driving uphill. Usually, the reason for pinging sound is the use of low-grade gas, other reasons are faulty turbocharger knock sensor, the EGR valve is faulty, or spark plug end cover is covered with carbon. What causes pinging sound in the engine The use of low-grade gas is causing a pinging sound Pinging sound usually causes an engine-related fault, however, there are several causes of pinging sound one of the cause is the use of low-grade gas. Low-grade gas is usually with 88 octanes or below. A gas with low octane burns too easily because it is too combustible and will self-ignite before it reaches the combustion chamber, this phenomenon is called “pre-ignition”. When pre-ignition occurs on the engine, you will hear a pining sound. When filling your car with gasoline always use a higher octane rating gasoline, usually 92 octanes and above, octane rating is disp...

If air barely blows out even with fan at the highest setting, it indicates a problem with the blower or physical blockage of ducts. Problem With Blower Whenever air barely blows out the vents, the blower (a.k.a. "fan") is always a prime suspect. In particular, the blower motor may be failing or the blower wheel may be slipping from the blower motor shaft. Another possibility is that the blower will only operate at it's the lowest speed, regardless of which setting it's on.  For example, even when the blower/fan is on its highest setting, it sounds like it's on its lowest setting. This is caused by a faulty dashboard blower/fan switch assembly (specifically, loose wires or bad resistors). Physical Blockage Of Ducts Obviously, if the ducts are blocked , airflow will be restricted. One possibility involves a heavy accumulation of leaves in the fresh-air intake port. However, this will only affect air output when the system is set to "fresh...

Car trouble symptoms There is noise coming from transmission while moving in two or more gears. If there is noise while you shift from two or more gears the reason is damaged input shaft bearings or main shaft bearings. Reason for noise while moving in two or more gears (1) Damage input shaft bearings or main bearings. As indicated in the above problem, noise occurs when moving in two or more gears. The key here is "two or more" and this points to a problem with something inside the manual transmission which rotates at all times. Since the input shaft bearings and main shaft bearings rotate at all speeds, they are likely candidates for the cause of the noise. It isn't positively stating that this is the cause of the noise but rather that it's a likely cause. There is really no way of knowing for sure until the transmission is opened up and examined by a professional. What to do? Regardless of whether the problem is with the input shaft bearings or main shaft bea...

If there is squealing or howling when letting clutch out, the problem often indicates the following. (1)Faulty throughout bearing or faulty pilot bearing Let's examine each of these possibilities. While releasing the clutch pedal, the clutch linkage pulls something called a throughout bearing away from the pressure plate. The pressure plate is then able to press against the clutch disc causing the clutch to become engaged. Now, as the throughout bearing is being pulled away from the pressure plate, it is rotating. If it's faulty, it will often make some sort of noise (commonly that of a squealing/howling sound - as you indicated in the problem you chose). In the second case, again, while releasing the clutch pedal, the clutch is engaging. This means something called the pilot bearing (connects the crankshaft to the transmission input shaft) will have stress on it. If it's faulty, it will similarly make a squealing/howling noise. By the way, if the noise is louder whe...
