2011 qx56 heater

[Jfb315]

My 2011 qx56 blows cold air from heater when the car is stoped Nd engine in. Works fine when I’m driving. Also you can hear water bubbling or gurgling when the weather starts to get cold out behind the dash. Has done this for years. No leaks or anything. Cant find anyone that wants to fix it. I was thinking air in the coolant system? Is there a bleader valve maybe? Please help thanks

mine did this too. I had to purge the air out. on the passenger side where the two hoses go into the cabin, there is a tube you can take off to get the air out. i parked so the front of the car is sitting higher. I attached a hose from the purge valve and just ran it back to the reservoir to cycle through the system and let the car run for 10 min or so. its worked just fine since then. ill see if I can send pictures tomorrow
