Volkswagen Golf 1994 260000 miles
In the morning, it is hard to start the engine and, once it does, the speedometer or cluster blinks. I have read that, in most of the cases, the problem is in the coil, but it can as well be in the fuel pump. Apart from that, the car overheats and starts whenever it wants. It is driving me crazy, I need your help please.

Here are a few things you can try:
Check the radiator. A radiator that is clogged or damaged can cause the engine to overheat. You can check the radiator by looking for any visible damage or debris and by checking the coolant level.
Check the thermostat. The thermostat is responsible for regulating the flow of coolant to the engine. If the thermostat is stuck open or closed, it can cause the engine to overheat.
Check the radiator fan. If the radiator fan is not functioning properly, it can cause the engine to overheat. You can check the radiator fan by turning the ignition on and observing the fan to see if it is spinning.
Check the water pump. The water pump is responsible for circulating the coolant through the engine. If the water pump is not functioning properly, it can cause the engine to overheat.
As for the issue with the heating system, if hot air is blowing into the cabin even when the heater switch is in the off position, it could be a problem with the heating system or a malfunctioning component.
Check the heater control valve. The heater control valve is responsible for regulating the flow of hot coolant to the heater core. If the heater control valve is stuck open or closed, it can cause hot air to be blown into the cabin even when the heater switch is off.
Check the heater core. The heater core is responsible for heating the air that is blown into the cabin. If the heater core is clogged or damaged, it can cause hot air to be blown into the cabin even when the heater switch is off.
Check the blower motor. The blower motor is responsible for blowing air into the cabin. If the blower motor is not functioning properly, it can cause hot air to be blown into the cabin even when the heater switch is off.
If you are unable to identify the source of the problem or if the issue persists after checking these components, I recommend having a mechanic diagnose and repair the issue to ensure that the problem is properly addressed and the vehicle is safe to drive.
