Altima 1995 falling apart

First things first, you need to see why the check engine light is back on. Just because you replaced 2 sensors a while ago doesn't mean one of the 40 others isn't going out of spec either.

As for the transmission, check the fluid level and make sure it's up to par and sniff it, if it smells burnt then have it serviced, otherwise, it could just be a lot of miles on it. the a/c sounds like the switch could be bad or the connector to it is loose.

for the jump starting, I'd have the battery charged and tested as well as the alternator.

Here's what I'd do.. Find an Autozone and bring the car to them and have them check the battery and alternator, they can do this on the car. IF the car wont' start do this. If the car turns over, but doesn't fire up, it could be a lot of things, but have the timing belt checked out. If it does start, head to Autozone. Also see if they have the means for the check engine light. Usually they just do the cars from 1996 on up, but they might do a car that's older.

Sounds like you don't take care of it...and don't care to.

Get rid of it. Then buy some cheap car because it sounds like you beat the s--- out of cars and the new one will no doubt be "falling apart" in a few years.

Altimas are well-made. I had a 94 until last fall and hardly ever had a thing go wrong with it. Same is true for many other Altima owners I know.

Actually I have taken good care of this car. I do not do any of the repairs but in the past 4 years that I have owned it I have replaced the entire exhaust system 2 times, oil change every 3000 miles, new battery and alternator, sun visor repaired, air conditioning repaired, driver side entry key lock replaced, oxygen sensor replaced 2 times, tires, have had 3 complete tune-ups one in which the dealer put in the wrong plugs which by the time this did its damage the dealership had gone under. I feel maybe the only thing I did wrong was to only have Nissan dealers work on the car. By the way, in the past 4 years I have owned the car we have put

12,000 miles on it. It is in the shop too much to drive it much. Our other car is a Toyota, which other than regular maintainance, I have not put a cent into for the past 3 years. So dont make assumptions about people.

Sorry to hear about you luck with the car. Some cars get built better than others, it's sort of a numbers game.

The air conditioner not working in any mode but full is a problem with the A/C Resistor pack, when the fan is in FULL mode, it by-passes this device to allow the full twelve volts to make it to the blower motor (which generates that wonderful gust of air). This part is also called the Blower Motor Resistor. The part shouldn't be too expensive, and replacing it should take 1-2 hours. I can't say for sure where it is on your year specifically, but it is generally placed by the blower motor, under the glove box. It will have about 5 or 6 wires going to it.

Nissans are somewhat notorious for less than great electrical systems, especially for wiring, and I've had my share of the problem. The strange noise you might be getting from the car when you attempt to jump it may be a very weak electric current running through the relays. In that case the problem tends to be a dead cell in the battery. When this happens the battery has a short in it and it absorbs all the juice from then car, hence jumping will not work. (This has happened to me). One way to check is to activate the Hazard Lamps (with the key off), if they dont come on, or create an interesting buzzing noise, the battery or it's connections are probably the problem.

I'd like to offer more help but I'd need to know what sensors are considered the culprit for the Check Engine lights illumination. Also, if you've replaced the same Oxygen sensor twice, there may be a fuel problem, either with a leaking injector, or with bad gasoline. Fuel injectors are actually pretty easy to replace on the Altima 4 cylinders. (KA24DE) The injector could be dumping too much fuel into a cylinder, and then setting the Oxygen sensor as failing in the Computer. This would definitely cause the Check Engine light to come on. But this is a vague guess to their premature failure.

Also, your car doesn't have a timing belt, it has a timing chain, which is very long lasting, generally 300,000 miles and then some, especially when she's getting a regular oil change.
