For those of us that make good use of our AC during these hot days do you find at some point when the AC reaches the proper cabin temperature that the fan slows down as it should but at some point the cabin starts to feel humid? I was told to put the AC on recirculate. But, some of the great minds at Jaguar have determined that recirculate should be timed. And.......the humidity returns and at some point it goes away during its own automatic recycle process.

Is anyone experiencing a similar situation?

There is a TOPIx bulletin JTB00380NAS3 "Inadequate A/C Performance". Is there anyone who has access to this bulletin??

It's mostly applicable to other Jags that are older. There is a minor part in AC compressor that can wear out. Probably not your issue but could ask an SA about it.

Also, the recirculate button is only timed if you press it briefly. If you press and hold, it latches recirculate on until you manually change it.

Hot as heck here in VA the last few weeks, and the AC has handled it well. You may have an issue.

The bulletin issued is specifically for the F Pace and possibly others but it came up when I put my VIN number in.

Thanks, that may at least be a temporary fix.

I haven't been super thrilled with the performance of the A/C. Especially when the Auto Start/Stop function is enabled - it really cuts the air conditioning quality down low.

AC and humidity

For those of us that make good use of our AC during these hot days do you find at some point when the AC reaches the proper cabin temperature that the fan slows down as it should but at some point the cabin starts to feel humid? I was told to put the AC on recirculate. But, some of the great minds at Jaguar have determined that recirculate should be timed.

Yes. I lower the thermostat setting, and keep reactivating the recycle option.

Haven't yet had any problems with my F-Pace A/C, here in 100F+ OKC. That said, I'm currently driving a 2016 XC90 dealer loaner and it fogs the windshield like crazy, even with the recirc/anti-fog function enabled.

There is a TOPIx bulletin JTB00380NAS3 "Inadequate A/C Performance" that has the fix, See below:

F-PACE (X761)
Model Year: 2017 Onwards
VIN: 045409 Onwards

So if you VIN is higher in number there is a fix.

In addition see Peter's temporary fix which is to press and hold the recirc button. Again I think that is a temporary fix. You should not have to keep lowering the temperature to get rid of humidity in the vehicle.

Tell your dealer to order the parts for the fix.

Is there any additional info that you can see or do we have to ask VZX to check? :)

My VIN is higher but for the week I have had the vehicle it has been hot in Toronto sometimes high of 85F more or less and even with the sunroof cover retracted no problem with the a/c. Maybe the fix was done during the PDI.

Stupid question: Where can we put in our VIN numbers to check on things? :O Is Topix a website that we can go to? I'm just about to google it but thought I would ask here to remind myself about it as well. Thanks in advance.

FWIW, my SA responded today and said they're ordering parts for the A/C system per the bulletin. Not sure what parts so I asked...more information to follow...

The bulletin was issued on July 15th so I doubt they did it.


For Other Forum Members:

This is part of what the bulletin says:

CONDITION SUMMARY:

Situation: Inadequate air conditioning (A/C) performance may be experienced with the (where applicable) working properly compressor clutch.

Cause: This may be caused by the A/C compressor Direct Pressure Sensing (DPS) valve being worn.

Action: Should a customer express this concern, follow the Service Instruction outlined below.

It then says the following part # should be ordered C2D51357.

If you have not experienced the high humidity situation then your vehicle is probably not affected.

Recycle mode is really just meant to cool down the car faster or to avoid a stink bomb. The longer you run that mode, the more humid the inside air gets which can cause your windows to fog up.

Technically it's more efficient because it cools already cooled down air (to a point), but if it's so hot outside that you want to run it in that mode all the time, probably means the car can't keep up to demand.

We never keep recycle on and it gets humid fairly quickly. Then it gets really bad when start/stop is engaged.

I have tried every combination to keep the cabin from getting too humid. I am very familiar with the different functions of the AC system. The latest thing I've learned is by holding the recirc. button as opposed to just tapping it is supposed to keep it on recirculaton. The problem still exists, so the bulletin above hopefully cure the issue for me and others that have the same problem.

Just an FYI it becomes so humid for short periods of time that my wife cannot drive in the car with me. So I hope the fix works.

Also, we learned that the AC system has a function to select a "Balanced" output or "Quick" (can't remember the exact labels). One blows air steadily and the other dumps it out very quickly to cool the cabin down, then tapers off.

Not sure which I would prefer, but my wife likes the balanced setting.

What if your VIN is lower in number?
