If you ever need to connect an aftermarket amp to your head unit, it might be useful to know the pinout of the amplifier which you will find behind the carpet trim on the left hand side of the boot.

You might need to remove the lock barrel if you have a problem with it or you are changing your locks. If so, this is how you do it.

Symptoms

• loss of coolant
• evidence of water spray in a circle around the fan - check the bonnet lining and sides of the radiator hoses
• dampness on the front of the engine underneath the fan (after the car has been sat for a few hours)

Symptoms

• temperature gauge not reading at 12 o’clock

Many of the switches in your car will illuminate when theheadlights are switched on, but most of them use tiny incandescentlight bulbs to provide the illumination. The problem with these bulbsis that they eventually burn themselves out. The repair procedure I’mgoing to describe here is to replace a burned out lamp with an LED.
