HEADLIGHT PROBLEMS


Both headlights are not working-- 
This is usually caused by lack of voltage supply to the headlights due to
  • wiring fault
  • bad headlight relay/fuse/headlight switch/dimmer switch/module
To know the exact cause of the headlight problem, retrieve your owners manual and locate the main fuse for the headlight circuit. If it'd blown, replace fuse with a new one but if it blows again like almost immediately, then there is problem in the headlight circuit that will have to be diagnosed and repaired before headlights will function again. But if the fuse does not blow and your headlights are still nor functioning, this is likely because there is no power at the fuse which would indicate a fault in the wiring either in the fuse block or between the fuse block and the battery
If there is voltage in the fuse, then it's time to inspect the headlight relay. You do this by pulling the relay out and shaking it. If something rattles inside the relay it means it's faulty, time to get another relay

One headlight does not work--This usually means the headlight bulb has burned out. Before replacing the bulb check for signs of corrosion or damage on the electrical connector on the back of the headlight
Most modern vehicle have headlight that changed from the back of the headlight housing. It is easy to access this housing on some vehicles while on some others you may have to remove lots of components before you get to the bulb. See your owner's manual to better understand your vehicle's headlight housing
NOTE: When changing the bulb, make sure it's the same size and style as the original one
CAUTION: Never touch the glass on a new halogen bulb with your finger because the oil in your finger can react with the quartz glass and cause the bulb to burn out prematurely, ALWAYS USE GLOVES

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...
