20 Most Recent 2003 Nissan Altima Questions & Answers


Just by the information you put, I would say its your brakes. They are most likely worn out past the minimum wear (3mm). If its whenever you drive maybe you are dragging something? Your exhaust system supports may have failed, maybe something stuck in there and so you are dragging it along. Take a look underneath your car.

If the noise only happens when you brake then its gotta be a problem with your brakes. Sometimes rocks get stuck in between brake pads and rotors, this makes a very annoying squeeling sound until the rock comes loose and falls out. Another possibility, like I said earlier, is that your brake pads have worn out and is now metal on metal. I recommend you go to a shop and get your brakes checked. Brakes are a very important part of your vehicle, safety especially, so I don't recommend doing it yourself unless you know what you are doing.

Hope this helps.
Thanks

:)

I was JUST working on a similar problem at work. It was a 2006 Altima SE with improper seat operation. It would ONLy go up/down on the bottom section of the seat. The recline and slide didnt work at all. It was looked at by different dealer and they couldn't fix it, so it end it up at my dealer ship. Since some of the features of the power seat are working, that means that you have power going to the switch. The switch provides ground for the whole circuit. The wires coming from the switch got chaffed and switch burned up. I installed new seat switch ($150 or so for the switch) and the whole seat bursted to life. I am pretty sure that you seat switch in NG.

The seal is easy compared to the axle removal. It is simply knocked into the transmission housing.

You didn't mention your engine size. This vehicle does not have a coil pack on either engine. This engine uses "Coil on plug" ignition coils. I am forwarding pictures for the 2.5L i4 and 3.5L V6.

This gets asked a lot, so I wrote a tip.

Want to bypass your vehicle security system?

The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system.

The immobilizer is in place to stop exactly what you are trying to do, boost the car and drive it away..

You will need two plastic wedges and a piece of stiff wire (wire coat hangars work remarkably well) or a slim jim.
Insert the wedges between the metal portion of the driver door and the window to allow easier access for the slim jim/wire.
Slide it to the location of the lock bar. Hook the lock bar and yank to the right. This should actuate the locking lever and unlock the door.
