Similarly, some Proton car owners have reported that none of the windows, except for the driver’s window, respond to the switch. This issue has been observed in various Proton models, including the 2004 Proton Impian 1.6auto.
Proton Distributor and ECU Spike
The distributor and the ECU (Engine Control Unit) are vital components of a Proton car’s ignition system. Any malfunction in these components can lead to various issues. Two common problems related to the distributor and ECU are a faulty distributor and ECU spike.
Faulty Distributor
In some cases, a new distributor fails within a week of installation. This problem has been reported by Proton car owners, who suspect that it may be a result of an ECU spike. The exact cause of the distributor failure is yet to be determined.
ECU Spike
An ECU spike is another potential cause of distributor failure. Proton car owners have raised concerns about the possibility of an ECU spike damaging the distributor within a short period of time. More research is required to determine the exact relationship between the ECU and distributor failure.
Proton Central Locking and Alarm Failure
The central locking system and alarm are important security features in Proton cars. However, some owners have experienced issues with these systems. Two common problems include a clicking sound without actual locking and a malfunctioning driver’s door button.
Clicking Sound but No Locking
Proton car owners have reported that when attempting to lock the car, they hear a clicking sound, but the doors do not lock. This issue has been observed in models like the 2010 Proton Persona gen2.
Driver’s Door Button Issue
In some cases, the driver’s door button does not function properly. When forced down, it immediately pops back up. This issue persists even after disconnecting all the door locks. Proton car owners have expressed frustration with this problem.
Proton Heating and Cooling Problems
Maintaining an optimal temperature within a car is crucial for a comfortable driving experience. Proton car owners have encountered issues related to heating and cooling, specifically after replacing the thermostat. Two common problems include inconsistent heating and temperature gauge fluctuation.
New Thermostat Installation
Some Proton car owners have reported that after replacing the thermostat, the car warms up properly when idling but fails to maintain the temperature when being driven. This issue has been observed in models like the 2008 Proton Impian 1.6 Campro manual.
Temperature Gauge Fluctuation
After installing a new thermostat, Proton car owners have noticed that the temperature gauge fluctuates when driving. It warms up initially, but as soon as the car is in motion, the temperature drops. This issue has been reported in various Proton models.
Proton Brake Light Fuse Blowing
The brake light fuse is an essential safety feature in Proton cars. However, some owners have faced issues with the fuse blowing, which is potentially linked to the central locking system. In some cases, the fuse blows as soon as the brake pedal is pressed.
Central Locking Activation
Proton car owners suspect that the blowing of the fuse may be connected to the activation of the central locking system when the brake pedal is pressed. This issue has been reported in models like the 2010 Proton Gen 2 1.6.
Fuse Replacement
To resolve the issue of a blown brake light fuse, Proton car owners may need to replace the fuse. However, it is crucial to identify and address the cause of the fuse blowing, which may be related to the central locking system.
Proton Water Pump Replacement
The water pump in a Proton car is responsible for cooling the engine. When it malfunctions, it can cause overheating and other issues. Replacing the water pump can be a challenging task due to limited space around it.
Limited Space for Replacement
Proton car owners have reported that replacing the water pump in models like the 1997 Proton Persona sdi can be difficult due to the restricted space around the pump. It is important to consider the necessary adjustments when attempting to replace the water pump.
Engine Adjustment
To facilitate the replacement of the water pump, some Proton car owners have suggested raising or lowering the engine[^7^]. This adjustment may provide better access to the water pump and simplify the replacement process.
Proton Key Recoding
The key recoding issue involves the automatic locking and unlocking function of Proton car keys. Some owners have reported that the car does not lock automatically from the key and manual locking or unlocking is required.
Manual Locking and Unlocking
Proton car owners have expressed frustration over the manual locking and unlocking process when the automatic function of the key fails to work. This issue can be a hassle, especially when the owner is accustomed to the convenience of automatic locking.
Automatic Key Functionality
To resolve the key recoding issue, Proton car owners may need to recode their keys or seek assistance from a professional. Recoding the key can restore the automatic locking and unlocking functionality.
Proton Petrol Injector Issues
The petrol injectors are crucial components of a Proton car’s fuel system. When they malfunction, it can lead to poor engine performance and an uncomfortable driving experience. Two common problems associated with petrol injectors include hesitation and staggering.
Hesitation and Staggering Problems
Some Proton car owners have reported that their vehicles experience hesitation and staggering while driving. This issue is particularly noticeable when accelerating and can make the driving experience uncomfortable. The exact cause of this problem is yet to be determined.
