Nissan Altima Serious Problems

Q. Hi Vincent, The most serious problem happened last Saturday evening. I have a 1996 Nissan Altima GXE, 4 cylinder, non-antilock brakes (front disk, rear drum), EFI, about 105,000 miles.

1) The red indicator lights showing both the Battery and the Brake came on at the same time. I looked at the master cylinder and saw that the fluid was at the full line. I bought a new Diehard battery about six months ago to replace the original Nissan battery.

The battery looked fine with no corrosion. Other than the two dashboard indicator lights, the car seems to be fine right now and drives okay.

Any clue to what’s wrong here? Could the new battery just be buying time for a blown alternator, with the car ready to conk out anytime? What about the brake indicator light coming on at the same time?

I had an 84 Toyota Pickup which had the brake light come on when its alternator blew. Could this be the problem with the 96 Altima too (you might have to trace the wiring diagram to check on this)?

2) Not as serious, the first three AC fan settings doesn’t work, but the fourth (the highest) setting works ok.

What can I do to get the other three lower fan settings to work? Could it be a fouled up switch?

3) Also not as serious for now. My exhaust leading into my muffler broke. I thought about welding the two back together. A Goodyear place that changed my oil said that the two could not be welded together and that a new exhaust system was needed (for the same 1996 Altima).

The Goodyear place came back with a $800.00 estimate to replace the exhaust from the Cat.Converter on back. This seems unreasonable. I would think the Nissan dealership would be even bigger than $800.00.

Any help here would be appreciated, as I am unemployed right now and can’t spend so much.

4) My Air Bag indicator light is red and flashes all the time. Are the air bags dead? I use the safety belts all the time anyway. Is repair here something I can do? If not, what about the probable expense?

Should I just get electrician’s tape and cover the light so it doesn’t distract me?

Thanks.

A. There isn’t anything here that’s too terrible. Let’s go by the numbers.

1) Those lights being on indicates a bad diode pack inside the alternator. The alternator itself is probably still charging and you can drive it like this for a long time. The only thing is, if the alternator dies, you won’t know it.

Replacing the alternator will correct this.

2) There is a blower motor resistor that controls the blower fan speed. When it goes bad you lose all blower speeds except High which is a direct connection. Replacing the blower motor resistor will fix this. It’s easy to replace. It’s in the heater box behind the glove box.

All you have to do is unplug it, remove two screws and take it out. Pop the new one in and you’re done.

3) Go to the Nissan Dealer. An exhaust system from the catalytic converter back is only about $550.00 plus 1.5 hours labor.

4) The flashing Airbag light is telling you it found something wrong. If it started flashing after you put in the new battery, it’s telling you power was cut. Like, no kidding.

The only way to reset the light is to have a Nissan Dealer hook up their CONSULT to the car, check and clear the codes.
