I wanted to start a stand alone thread for anyone having this same issue and so that people are aware a case has been started. The issue I am having is that when the car is first started in the morning and the fan is on the auto setting, as the car warms up and the fan should start to blow more the display shows that the fan should be blowing at say 75% but nothing is blowing. At this point I can change fan speed, temperature, really anything with the HVAC control and nothing engages the fan. If I simply turn off and turn back on the HVAC system it then begins to work. I got this on video and took it to my local Nissan dealer for them to investigate and start a case. This happened about 6-7 times this winter with all but one of them being on very cold mornings in the mid 20's or lower. I did have a single case happen in September when the A/C was on that required the entire car to be shut off before it would re-engage the fan but that has not been repeated.

I got my Pathfinder back after being at the dealer for about a week and a half with no fix. They certainly did their due diligence and went back and forth with the Nissan tech line for quite some time checking over various items and also trying to replicate the concern. The service manager suspects that I may be a software issue given all that they checked. If enough people report this to Nissan it will certainly increase their chances of looking into it more and providing an actual fix. If anyone is having this same problem I would suggest getting it on video to provide to your Nissan dealer and you may refer to tech line case #45871540 to reference the one we started.

Sorry if I missed it, but do any brand new pathfinders sitting on the lot exhibit the same behavior? If so, it's "programmed" in to do so. Probably to allow the system to build up some heat or cold.

I have the same issue…. Pathfinder HVAC Issue

Have you gotten any movement from Nissan? It’s not a huge deal but I’d like to get it fixed. I can’t seem to figure out what causes it. Hoping they don’t have to open the dash up to fix it!

I haven’t reached out to the dealer yet - do you have a contact at Nissan I can email?
Mike, I would just work through your local dealer and let them know the case number and what is going on. Try and get it on video so you have actual evidence to provide them as it will be extremely hard for them to duplicate the issues with how randomly it happens. There hasn't been any fix yet and honestly I'm not holding my breath that there will be. I at least wanted it on record so if I'm out of warranty and something drastic goes wrong with the HVAC I have some evidence that I've had issues from day 1.

Not that, otherwise the fan wouldn’t show that it’s on full blast. Also it happens too intermittently for it to be normal behavior.
I'm not saying it's normal, but in auto mode, the fan may show full beans on the display, but that doesn't necessarily mean the control system is going to allow the fan to run at full speed until some conditions are met. This is how some of these systems work when in auto mode.

Again I ask those of you that have pursued this with the dealer. Do all new Pathfinders on the lot do the same thing?

There is no case where the fan should show full blast and not be going full blast. When it is an auto mode yes the computer limits the output until the car is warmed up but it always lines up with what the fan display says the fan speed is. It typically shows 1 maybe 2 bars until adequately warm then goes up from there. Additionally if I take it off of auto there is still no control over the fan speed. The dealer said this is absolutely not normal operation and that it should not be happening.

As far as if all Pathfinders do this, it would be impossible to tell. This is not normal behavior but it's so random and rare that there's no way to tell if any on the lot do the same thing without living with them on a daily basis for months.

Hopefully Nissan can sort it out for those effected.

I have basic manual controls w/ rotary dials on my 2019 Ram 1500 pickup. I can change modes and wing the fan speed all the way up to max and the system stops, thinks about it for a bit, makes the mode changes, then ramps the blower up to max. This process can take maybe 5-10sec but it is consistent and it works every time. Even though it's the basic HVAC system, it's still entirely computer controlled.

I do agree that the HVAC system on any R52 or 53 Pathfinder is overly complicated and there are many posts of issues with it here. I can't stand the system on our 2019 Pathfinder SV, but I'm basically never in the vehicle since it's my wife's car, I'm just 100% responsible for it. LOL

It would be nice if the concern you guys are having is as simple as low system voltage (faulty battery, etc), which will cause all kinds of odd issues.

I also wonder if it's autoamp related, assuming the R53s share the same autoamp as the 52s.

I just wanted to add that I also have some variation of this problem. While I haven't seen the thing where the car says that it is blowing at full blast but isn't, what happens for me is that the HVAC, when set to auto, randomly will not start blowing warm air even long after the car is warmed up. I notice that it usually takes around four minutes for it to start blowing warm air from a cold start on a cold day, but on days when I'm experiencing the issue, I can be 10 minutes into the drive and it is still not putting out any hot air. Turning the system off and then on again instantly results in warm air blasting out from the vents as it should. I should also mention that I have noticed some other issues with the HVAC system including an AC compressor that went out and was replaced under warranty and some vent sounding like it is repeatedly opening and closing that is also resolved by turning the unit on and off again. It would be nice if someone ever gets this issue escalated to the point where a fix comes out.
