replace the fan motor but first check the relay

The most likely cause is a broken speedometer cable. On a lot of older vehicles, it is very difficult to get access to it. It depends on how long it takes to remove the panel of cluster gauges. That is the hardest part of the job. You might have it easy if there are screws that come out that hold just the cluster gauges. Otherwise it can be a major job that can take several hours to do.

It may be worn out valve lifters that are inside the engine. If you have more than 6,000 miles on the oil, valve lifters could run noisier. Changing to a high mileage type of motor oil may quite down the valve lifters noise somewhat. Synthetic oil used during the summer months could make it noisier too. If you can hear the noise while driving the car, it is not normal. Upon acceleration, if it gets noisier, you will be needing a valve job in the not to distant future.

check the signal at the sensor with a multimeter. Most have three wires, one is a 12volt feed, one is a ground and the third is the signal wire. This wire is usually only 5volts and is grounded and ungrounded by the sensor in precise timing intervals as the sensor rotates. This means that to check its operation, make sure it has the 12volt feed and the ground, then, Jack up one rear wheel and chock the rest. Select neutral and release the parking brake. Turn the ignition on BUT DONT START THE ENGINE. Reconnect ALL the wires to the sensor and then backprobe the signal wire you found earlier with a multimeter. Once you have the wire probed, slowly rotate the wheel by hand. The meter should show the 5 volt drop to nothing, then back to 5volts, then nothing, then 5volts and on and on as long as you rotate the wheel. If this 5volt is not present, check the instrument cluster as this 5volts comes from the speedo head. If the 12 volts is not present, check all fuses WITH A TEST PROBE - looking at the fuse is not enough and check the wiring to the sensor. If the ground is missing, check the earth point on the chassis under the rear of the cab and under the bonnet and repair and issues found.If all these tests show good and you have the alternating 5volt voltage, check the same signal wire at the cluster, if it still alternates when you turn the wheel by hand, repair the speedo head. If the 5volt signal feed from the speedo head is missing, check the wiring to the speedo head, if the signal is not present at the speedo head, repair the speedo head.

I would be checking to see if the cam shaft is turning as I suspect a broken timing belt.

If this is the Air Bag fault light, then have your vehicle checked out and repaired for a failure in the airbag system. Your air bags may not deploy in an accident if you don't get it fixed. When you start your vehicle, the computer checks for the presence of an undeployed airbag. If it doesn't see an airbag it will turn on the light. This could be something as simple as a poor connection. If your planning on driving your can after an airbag deployment, this may be a legal issue, depending on where you live. Legal issues would also apply if your trying to sell a rebuilt auto, without airbags.

Could be a coolant leak into the cylinder. (head gasket leak) use a five gas scanner to check for hydrocarbons in cooling system.
