Newer Toyota Camrys are equipped with a bell that warns you to put on your seat belt before starting the car. Some people find it annoying and wish to turn off the chiming. There are instructions in the owners manual on how to do this. You dont need any special tools to turn off this seat belt warning and it will only take a few moments of your time.

Instructions

1

Put the key into the ignition and turn it to the on position, but do not start the engine.

2

Look for a tiny knob on the instrument panel and press it to toggle between the odometer reading and the trip odometer reading. Keep pressing the knob until you see "ODO." Turn off the vehicle.

3

Turn the ignition on but dont crank the engine. Pull the tiny knob out for 10 seconds. While still holding the knob out, put on your seat belt and keep holding the knob for another 5 seconds then release it. The instrument panel will now read "B off."

4

Repeat the above procedure to turn the seat belt warning chime back on.

The distributor on the 1985 Chevrolet Camaro is the main component that the spark plugs receive their voltage from. The distributor also supplies the proper firing order to the spark plugs to keep the engine in time. The gears on the bottom of the distributor shaft are turned by the camshaft. As the camshaft turns the distributor shaft, the distributor shaft turns the rotor inside of the distributor cap. The rotor then turns inside of the distributor cap and supplies the spark plugs with the proper amount of voltage to keep the engine timed.

Instructions

1

Park the 1985 Chevrolet Camaro in a safe working area and open the hood. Shut the motor off and engage the parking brake.

2

Raise the hood and prop it in place. Locate the distributor cap near the back of the engine. All of the spark plug wires are attached to the top of the distributor cap.

3

Mark a straight line on the front side of the distributor cap with a marker. Also mark another straight line on the front side of the distributor cap base directly below the other line. This will help you remember the exact setting of the distributor before moving it.

4

Loosen the hold-down screws on the bottom side of the distributor with a Phillips-head screwdriver.

5

Grab the distributor with both hands and turn it clockwise to retract the timing. Turn the distributor counterclockwise to advance the timing. Be sure to make short turns when turning the distributor. Once the distributor is timed to your liking, screw the hold-down screws back down tight with the Phillips-head screwdriver.

Since its introduction to the automotive world in the 1940 Packard, air-conditioning systems have been through many changes. The most drastic change was the shift from R12 to R134a, due to environmental concerns. When you turn on the air conditioner by pressing the power button and turning on the fan, you expect to hear the compressor kick on. There are six main reasons for the compressor not to turn on when you expect it to.

Incorrect Charge Level

All air-conditioning systems use a refrigerant to cool the cabin of the vehicle -- either R134a or R12. All post-1996 vehicles use R134a and prior to that, most vehicles used R12 refrigerant, commonly called Freon. The air-conditioning system requires a specific amount for refrigerant to run without causing damage. If the charge is low, most cars cut off power to the compressor to keep it from turning on.

Failed Pressure Sensor

Air-conditioning systems are under high pressure -- some exceed 200 psi. If the system has too much or too little pressure, damage may occur. Most modern vehicles use an air-conditioning pressure switch to monitor the pressures and cut power to the compressor if the pressures are incorrect. If this switch fails, no power can get to the compressor and it will not turn on.

Failed Wiring

The air-conditioning systems in all cars have a series of power and ground wires. If one of these wires fails, the compressor cannot receive power and will not turn on. This failed wiring can also cause additional problems with your vehicle.

Failed Air Conditioning Switch

To engage the air conditioner, you must press a switch inside the vehicle. If the electronics inside this button fails, the compressor will not turn on, as it will not receive power.

Blown Fuse

As with all electric systems in vehicles, there is a fuse that protects the compressor from power overload, typically 10 to 30 amps. If the amperage exceeds the limits of the fuse, it will break the circuit and the compressor will no longer receive power.

Failed Compressor

The compressor has a clutch on the front that engages and disengages as you turn the air conditioning on and off. If this clutch fails, it causes the compressor to either lock up or spin freely. If the latter is true, the compressor cannot turn on, as the power is not transferring from the drive belt to the compressor. If the former is true, the pulley locks up with the compressor and you will hear a loud screeching sound from the belt spinning on the stuck pulley.
