Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Is the air blowing out of the correct vents when the AC is on
Does it blow cold at all
Are ya still with me?
I just need that info to help narrow this down
If its blowing cold and out the correct vents then that will take me to a specific area.
Would you like me to call you?
Unless we can talk on the phone this is the best method.
Using your info, being that the hissing comes about with the AC or heater on, i am highly suspecting it to be a leaking vacuum hose in the engine area and gets transfred thru the firewall to under the dash. Vacuum leaks are very inexpensive to repair, but you have to be able to track it down by listening to it. Like i said my bet is its a vacuum leak and when you take it in for the AC service they can inspect that easily and wont cost much at all. SImple fix, just hard for me to pinpoint online because there are a few different areas that can leak vacuum and make that hissing.
No big deal at all and they will spot it real easy.
If further questions just let me know.
Thanks for asking!
And you do the same.

Let me know if the site wont let you choose a rating star please.
You are welcome but were you able to rate my service. If you are having trouble doing that just let me know.
It's VERY important to me. I have worked professionally for over 35 years and am a Master Mechanic and i do this to help people save me money but i do expect just a little for my time otherwise i cant help people out like this and you would have to depend on a "willy Nilly" answer from some site that does not have real pros online. I am a Vietnam veteran that helps Vets by getting there car fixed for next to nothing and that is my goal in life....to help as many people as i can before i die of cancer from chemicals during the war. I'm not giving you a sob story, just letting you know that i donate any money i make here online to My car charity to help the unfortunate. God Bless.
