Question about 2004 Nissan XTerra

1 Answer

I have a 2004 Xterra (4cylinder)...AC

The AC makes noises and it can't quite keep up with the heat. I bought a recharge can from Autozone but can't find the low side service port. What I've found is a rectangular shaped thing under a blue cap...but the recharge can has a circular nozzle. What exactly am I looking for?

2004 xterra makes clicking noise when AC is on. Blows cold air. When AC off no clicking noise

Try simple first, make sure it isn't frozen up and the click is the fan skipping off of ice wet spot under your car when you are parked for a few min is a dead give away, or water sprinkles blowing through vent when way over full, clear drain ports when thawed out also check to see if something went down vent.

Ratting noise from heat sheild

It's a common issue with most people just removing the heat shield(s).
I bent mine out of the way and used a hose clamp to keep it quite.
Hit up for more help (I'm rjr162 on there).And since it's a 2000, I'm guessing you have over 100,000 miles on it.. have you had the timing belt, water pump, bypass hose etc changed yet? If not, do it! Interference motors and broken timing belts don't go good together!

My 2004 Nissan XTerra makes a loud screeching noise when I turn on the AC, almost like its about to blow up or something. I was told that sounds like the compressor. How do I repair this myself?

You won't have the training/knowledge or equipment to work on a refrigerant system.
So you have to go to a shop that does, and won't pollute the atmosphere with refrigerant.
What caused the compressor to sieze up is the question. The entire system will have to be flushed, one component at a time,in case the compressor sent trash up stream.
Need you plastic for this job.$1500 min.

2004 Saab 93: A/C doesnt turn off, car now wont start

remove the AC relay to shut the AC off all the time. Not sure why it wont start but you may havea security lockout. Fully charge the battery to proceed.

Whining noise when AC or heat is on coming from engine compartmen

I suspect it is the blower fan and the ductwork for the air intake to the blower picks up the air in front of the engine compartment.

It would also be a good idea to have your alternator checked and use the A/C heat controls to see how much the blower motor is demanding from the alternator. Autozone and Oreillys will check the alternator on the car for free.

A rattling noise

I had rattling noises as well (over bumps and when I reved the engine) and it turned out to be the heat shields under the car. I took out 2 heat shields covering the two cats on both sides AND two rusted out dangling rings hanging from the exhaust coupler (have NO clue what they were for)..This has TOTALLY gotten rid of the rattling noise. Good luck!

Air Condition Quit on Beetle

Well, the beetle itself has a weak connector on the AC pump itself. You'll need to check the connector on the pump. It sits right on the top just to where you can get it. If it gets any type of oil or water on it will drive you NUTS. Mine did the same thing to me. I unplugged it and cleaned both the connector and the plug itself with a toothbrush. I haven't had a single problem since. Also, since it's a 98, it's probably time to recharge the AC anyways. You can get a recharge kit at autozone for around $40 I believe or you could have a mechanic do it.

As for the gas cap; it's possible the linkage popped off the actuator. That being the case, I believe you'll have to remove the plastic wheel well under the passenger rear tire to get to it. I can't remember if you can get to it through the trunk, but I'm pretty sure you can't. It's not the greatest of designs to resist wear and tear but it does work. It's not a fun process of getting to it; but sometimes you gotta do what you gotta do. lol

I hope this helps you out!
