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...

BRAKE FAILURE

Brake failure is one of the scariest things that can happen while driving vehicle and they even though they are rare in regular vehicles, they can happen without warning. You stomp down on the brake pedal to apply the brakes but the pedal goes all the way to the floor and there are no brakes WHAT DO YOU DO? Every driver should know whether or not they have anti-lock brakes or regular brakes. If you have a logo that lights up whenever you start your car that says ABS(antilock braking system) then you have anti-lock brakes, if not, you have regular brakes. If your brakes go out, you want to do three things. First, downshift to a lower gear. Second, if you have regular brakes pump the brake pedal fast and hard to build up brake fluid pressure. If the brakes haven’t started working after three or four pumps go on the step three which is use the parking brake. Gradually apply the parking brake and be prepared for the car to skid. If none of the brakes work, put the car into a low gear...
