Diagnosing the Problem: Is It Really the Wiper Motor?

Before you go ordering parts and getting your hands dirty, you need to be sure the motor is actually the problem. Sometimes, the issue isn't as complex as a motor failure; it could be something much simpler. Here's a systematic approach to diagnosing the issue with your JAC A137.

Checking the Obvious: Fuses and Relays

Start with the basics. Fuses are designed to protect electrical circuits from overloads. If the wiper motor isn't working, the first thing to check is the fuse. Locate the fuse box in your JAC A137 (consult your owner's manual for its location; it's usually under the dashboard or in the engine compartment). Look for the fuse specifically for the windshield wipers. It will be labeled. Pull it out and inspect it. Is the little wire inside broken? If so, replace it with a fuse of the same amperage rating. Never use a higher-rated fuse, as this could damage other components or even cause a fire. If the fuse keeps blowing, you likely have a short circuit somewhere in the wiper system, which means it is probably time to search the JAC A137.

Next up are the relays. Relays are like electronic switches that control the flow of electricity to various components. The wiper system uses a relay to control the power to the motor. Like fuses, relays can fail. You can usually find the wiper relay in the same fuse box as the fuses. You might be able to swap the wiper relay with another relay of the same type (like the horn relay) to see if that solves the problem. If the wipers suddenly start working, that relay was the culprit. Remember to replace it with a new one. It's critical for your JAC A137.

Inspecting the Wiper Arms and Linkage

Sometimes, the problem isn't electrical but mechanical. Check the wiper arms themselves. Are they securely attached to the pivots? Can you move them by hand? If they're loose or stiff, the wipers won't work properly. Carefully inspect the wiper linkage – the system of rods and joints that connects the motor to the wiper arms. This linkage can seize up due to rust or lack of lubrication. If you find any stiffness, try lubricating the joints with a penetrating oil like WD-40. If the linkage is severely damaged, you might need to replace it. A good inspection ensures a good JAC A137 car maintenance.

Listening for the Motor

When you turn on the wipers, listen closely. Do you hear any noise from the motor? If you hear a humming or clicking sound, the motor is likely receiving power but is unable to move the wipers. This could be due to a mechanical obstruction (like a seized linkage) or a problem within the motor itself. If you hear nothing at all, it's possible the motor isn't getting power, or the motor has failed. Test the motor by connecting it directly to a 12V power source (be careful and use proper safety precautions). If the motor runs when directly connected, then the issue is likely in the wiring, the switch, or the relay. Understanding your JAC A137 will help with all kinds of maintenance.
