I'm having the same problem- last 10 days. Very loud hissing sound that seems tpo be coming out of my vents on my 2009 Pathfinder
. Have owned 5 pathfinders. never had this happen before. have an appointment to check the charge on my AC next tues. This happens whether my Ac is on or off. Even when I tried when I tried putting the heat on high
JA: HHave you checked the coolant
level? Has there been any leaking from the hoses?
Customer: Coolant level is good.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: No Can't even find all the spark plugs
........LOL Taking it to a shop to check the AC pressure and maybe get them to change the expansion Valve.
JA: Anything else you think the mechanic should know?
Customer: AC still blows very cold. But not sure how long this will last if the freon is being depleted every time it has a hissy fit.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Nissan Mechanic about your situation and then connect you two.
