AIR CONDITION COOLING PROBLEM

If you are having problem an AC cooling problem, it is likely that your vehicle is lacking refrigerant in the system mostly due to leakage. Check for leaks at the compressor, evaporator and around hoses. It must be identified and fixed before refilling refrigerant

A lot of systems are designed to switch the compressor off when there is a low level of refrigerant, this protects the compressor from serious damage due to lack of lubrication

NOTE; Some seepage of refrigerant is normal for vehicles, the older your car the higher the seepage
An easy and old school way to check for leaks is to spray soapy water on hose connections and watch for bubbles
The chart below shows other possible diagnosis for your AC problem

If your AC blows cold air for a while and then warm air, it means your AC may be freezing up as a result of moisture and air allowing ice to form in the system and blocking the orifice tube.To fix this the air and moisture needs to be purged out using a vacuum pump until the AC system contains less than 2% air( this is required for optimum performance

DIFFERENCE BETWEEN FOOT BRAKE AND HAND BRAKE

Motorists around the world know how to use foot brake and hand brake, even non-motorists are aware of their operation but how many are actually aware of the working mechanisms of braking using the pedal and the handbrake? very few, i guess. So without wasting much time let's break down the difference Foot Brake and Handbrake: The Real Difference If you have always been looking for the answer to- “when should I use handbrake and foot brake,” then delve deeper into their mechanisms and find the appropriate answer? 1. Overview Commencing with the foot brake system, it is a pedal connected to vacuum booster, which is used to stop or slow down the vehicle’s motor. This is also known as the system of hydraulic brakes that multiplies the foot-force applied in order to stop a car weighing several tons. Whereas, the handbrake, also known as the parking brake, or emergency brake; is a straight pull handle near the steering column. This can also be a hand-operated lever...

BATTERY KEEPS RUNNING DOWN

You get home, park your car, do some stuffs and go to bed only to wake up the next day and discover your battery is dead. Here are some of the likely culprit PARASITIC DRAIN This means there is something drawing power from your battery while it's parked. If you have your stereo presets, security alarms or clocks running after the engine is off, it can drain your battery. This type of drain is known as parasitic drain. Parasitic drains below 75 milliamps are considered normal, but any parasitic drain over 75 milliamps will drain the battery quickly. The most common causes of parasitic drain are under hood lights, trunk lights, headlights or glove box lights that do not turn off when the door is closed. Relay switches that are stuck in the “on” position can also cause a battery to drain FAULTY CHARGING SYSTEM A faulty or unreliable charging system can also drain the battery while the car is running. When an alternator is not pushing out enough voltage, which should be betwee...
