Autotech sponsor febi bilstein discuss failing water pumps and faulty A/C systems.
Water pumps are sometimes overlooked during routine maintenance, but they can, and will, fail if left untouched for a long period of time. To keep an engine healthy in both hot and cold conditions, it is vital that the engine has a healthy supply of coolant and the water pump is the core component responsible for this circulation.
Symptoms of a failing water pump might be water leakage or the engine overheating. When the water pump starts to leak, it can often be due to the gasket or bearing deteriorating where the pump and engine block joins. If the pump fails completely, it can prevent the supply of coolant to the engine, causing the engine to overheat. Broken off or corroded impellers within the pump is another reason they fail.
When faulty, the pump can loosen and create screeching, high pitched sounds. This is often caused by the bearing operating the water pump, which starts to wear out. It is important to replace this part if this symptom occurs, as once bearings fail inside the water pump, it often means the unit cannot be repaired, and a complete replacement would need to be carried out. Worst case scenario, the engine can completely fail if not provided with the substantial amount of coolant, directed by the mechanism of a water pump.
If any of these symptoms occur, it is advisable to replace the water pump and use recommended coolants.

The heater blower motor resistor, part number 102584, is a popular reference for this model, managing the speed variances of the blower motor. Without this part, the speed of the airflow from the blower motor cannot be changed or may not work at all. If the resistor is faulty, it’s likely that the fan will only work on the highest speed. The fan speed is adjusted very frequently, undergoing a huge amount of stress which, over time, can ultimately lead to failure. A failing Blower Resistor can cause many problems with the heating/air conditioning and would indicate the need for replacement.
If the fan is stuck on high, it’s likely the heater blower motor resistor is worn or faulty and should be replaced. All relevant electrical circuits need to be fully inspected to verify a faulty resistor. Other symptoms of failure may be that the blower motor stops functioning (no air leaving vents), or the blower motor only operating at two speeds, instead of four.
Note: The highest speed setting may still work because in most cars in the highest fan speed settings, the current bypasses the blower motor resistor.
