Infiniti Repair Information

We'll help you out with everything you need to know about your Infiniti vehicle.


Recurrent Diminishing Tire Pressure

If your tires consistently lose tire pressure but they don't have any leak or puncture, then you may want to check the Schrader valve. To replace the Schrader valve, you will need a Schrader tool and a new Schrader valve. Remove the valve cover to access the Schrader valve. Fit the tool inside the valve and around the Schrader. Then unscrew it counterclockwise until it is unthreaded. Place the new Schrader in the valve and screw it tight with a clockwise motion. We recommend putting an extra 1/2 torch to secure the Schrader valve. Lastly, place the valve cover and tighten.

Faulty Power Seats

Can't feel the convenience of your car's power seats? Look underneath the seats-maybe an object is stuck and keeps the seats from moving forward or backward. Check the fuse and circuit breaker as well. Turn the car's ignition switch without igniting the engine. Try to operate the seats and listen if the motor under the seat is running. If you don't hear any sound from the motor, check the switch from the side of the seat. Using a test light, inspect for incoming voltage at the switch. If there is none, the problem must be a short in the wiring. Although this wiring issue can be resolved easily, you still need to refer to the wiring diagram of your power seats, which can be found in your vehicle's service manual. In doing so, you can effectively repair or replace the wiring.

Exhaust Leak

The first thing to do when there's an exhaust leak is determine which pipe is leaking. We recommend letting the car cool first because metal expands when heated, and this can close small holes during inspection. Cover the tailpipe to find the leaks. Without touching the exhaust pipes, feel any air getting through the pipes. Be very cautious when doing this because the exhaust is hot and may burn your skin. Start looking for leaks at the engine and follow throughout the exhaust system up to the end of the tailpipe. Don't forget to check the connectors and gaskets as well. These parts are usually prone to leaks. Once you have found the leak, turn off the engine and let the car cool before replacing the leaking part. Remember to replace the connectors or gaskets directly attached to the leaking pipe to ensure a smooth exhaust flow.

Faulty Brake Lamp Switch

Replacing this part yourself is easy. The first step is disconnecting the negative battery terminal to access the brake lamp switch, which is located just under the dash. It is near the pivot point of the brake pedal arm. Once you see the lock nut, loosen it until it is completely removed. When you see the two-wire electrical plug connected to the back, disconnect it. Remove the switch from its bracket and install the new one right where the stock switch was placed. Make sure the new brake lamp switch is connected to the two-wire electrical plug. Also, reconnect the negative battery terminal. To check if the connection is working, start the engine and press on the pedal to see if the switch lights up the brake lamp.
