2005 Pathfinder Heater

I have a 2005 Pathfinder with an automatic temp control that is blowing cold air even when set at 80. Dealer has said that I have a leak in the rear coolant lines. I have no evidence of leaks on my garage floor. The dealer claims that to repair said line they have to remove the entire body off the frame. Does this make sense to anyone??? When I first took delivery of the car it had the same problem and they repaired the blend valve. Couln't this be the same problem.

    Did you ask the dealer to show you the leaks?



    Is there a gurgling sound from the dash when you first start the vehicle or turn on the heater? Have you ever had to add coolant to the overflow bottle?



    It is true that the body needs to be lifted off the frame a few inches on the right side to get to the line, but they should make double sure that this is the source of your problem before charging you for the repairs.

Just had the same problem and got the same answer about removing the body to repair. Apparently it's an integrated set of lines serving both rear heat and cooling. Very expensive and not covered by extended warranty. My dealer was able to isolate the corroded heater line at the rear wheel well. They cut out that section and replaced it with a rubber hose and clamps. It worked for heat, but if AC lines suffers the same fate, there is no option other than the very expensive full line replacement.

WHen we use the auto car starter, it blows cold air, and a lot of it. Its nearing the winter here in New England and I need to know how to set up the starter to blow warm air. Any ideas?


Start the vehcle and let it warm up then set all the controls to heater? Then turn off the car. Use the remote start to start the vehicle and check the controls are still set to heat mode.

Passenger side blows hot air when front control set to Air


you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

2005 Pathfinder Heat Flow problem


I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.

I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.

But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!

As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!

Hope this works for you, and I hope I can figure out my rear heater problem as well.

A/C Heater problems


There is a motor that operates a door to change the air temp to the drivers side based on the setting of the temp control, it is called a blend door motor, there is a problem with the motor or the blend door is jammed and can't move.
