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

BRAKE WARNING LIGHT

When your brake warning light is on, it could mean a number of things, i. If the light is on all the time, it could mean you simply forgot to release the parking brake ii. If the brake warning light remains on when the parking brake is released, it could be that the switch on the parking brake pedal or lever is misadjusted, a simple adjustment should fix the problem iii. If the light is intermittent and seems to come on and off depending on whether the vehicle is turning, it may mean that the brake fluid level is getting low iv. If the brake warning light is on continuously, it means that hydraulic pressure has been lost in one side of the brake system or that the fluid level in the master cylinder is dangerously low most likely due to leakage. The fluid level in the master cylinder should be checked. Adding brake fluid to the master cylinder reservoir may temporarily solve the problem but if the culprit is as a result of leakage, the new fluid will soon be lost and the warni...

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...

AC PROBLEM; TROUBLESHOOT NOISE AND ODOR

It is not uncommon to see motorists complaining about noise and odor oozing form their AC NOISE--If the noise is coming from your compressor, it's usually means your compressor is wearing out or serving it's final days. This noise could also be the result of contaminated refrigerant, using the wrong type compressor lubricant and air in the system Noise could also be caused by parts of the system like the hoses rattling against other components in the engine ODOR-- If your vehicle air conditioning blows out funny air, the most likely cause is fungus, molds and/or bacteria living in your vehicle's climate control system (typically they congregate in the evaporator core and/or near the condenser in your A/C unit). These critters move into these areas because it's a moist enclosed space, and while some cars have a bigger problem with this than others, it's very common To get rid of the unwanted organisms, various chemicals like lysol antiseptic spray can be spra...
