A/C Smell and door issues

This is my first forum posting.

We purchased our 2017 Pacifica at the end of June. 109 miles on it. By 2K there was a mildew smell that would blast out of the a/c when we would turn it on. Husband called and was told that it happens "give it six months." The car went in for service two times since then; and both times he's asked about the smell. Changed the cabin air filter one time -- no fix. Then used a canister of some kind of stuff the service department gave him that was supposed to fix it -- nope. He was told that to run this problem down would take 2 days and that if the canister didn't work that the service department would do it. SO, we are now at the end of December; and the problem still happens sporadically (it's never been 100% consistent). Just picked her up today and they still will not work on tracking down the problem. Has anyone else had issues with a mold smell coming from the a/c of their new Pacifica? It's embarrassing. HOW did you get the dealership to finally address the issue. We are VERY certain that the dealership is trying to kick the problem down the line to avoid warranty work.

And we too are having the sporadic issues with the passenger sliding door losing its automatic functioning. Can't figure out a consistent cause or cure.

Still love the stow and go and the space that we have. Kids range from 4-8" to 6'-1". So space and head room were large concerns in our car search. Just never thought mildew would be an issue.

Hi okctorres,

Sorry to hear about this! If you decide to make another service appointment for further diagnosis of your concerns I'd be happy to offer assistance if needed. Just send us a PM with your VIN and let me know.

Turning on your air conditioner to maximum often may cause bacteria growth due to the excess water that is dripping in your unit.

To fix this problem, locate the drain tube in your A/C unit. Make sure that is working properly. Use an anti-bacterial treatment that will destroy bacteria that is growing behind your dash panel. Inject the treatment solution into the air conditioner case. It is advisable to turn off the car air conditioner for awhile and let the fan run instead for a few minutes. This will help evaporate the water on the coils of your unit.

Yes we have. We are at about 44k and have an occasional awful moldy smell. I haven't figured out the pattern yet - it seems to appear regardless of the weather or what vent selector we use. It's there for awhile, then gone. Sometimes it starts ok, then starts stinking. I haven't been to the dealer on it yet. Just not sure what to do.

Hello everyone,

Just to chime in, there is a Star Case for the 2017 models and relates to the odor smell you're referring to. If you'd like to work with the dealership, feel free to send us a direct message and reference this message. We'd be glad to get this process started.

We took our 2017 Pacifica in 2-3 weeks ago for a very strong mold/vinegar smell. They said they made sure all drains and lines were cleaned and cleaned out the vent system. This seemed to last 2-3 days and then the smell returned but less smelly. We then changed the air filter as it was not changed at the dealership to see if this would fix the issue and it did not. Yesterday we again took it back and the first response we got was “we could not replicate the problem” so this am we went and sat in the van with the service manager and the smell was clearly there. The service manager replied “oh this is going to happen after the car sits due to the humidity, you have a big air box” and that “this is normal”. My husband drives an Xl Youkan which also has a large air box and we have yet to have an issue with it having a mold or mildew smell. I have also had older vehicles that have never had this issue so I’m confused as to how “this is normal”
Very frustrated with this entire experience. It’s getting warmer and I won’t be able to drive with the windows down much longer.
I’m totally bummed to say the least and was planning on a future Pacifica after my lease is up because I love the van so much but I cannot do this if the issue is not resolved. I feel like my health and my 3 young kids health is being compromised do to this issue.
I am hoping there is some other way to resolve this issue because the dealership is not willing to do anything at this point.

It is true that in high humidity environments that mold can build on evaporator coils and cause an odor, especially if the van sits for a couple of days between drives. I make it a practice of turning off the A/C the last few blocks on the way home to blow some warm air through there to dry it out a little in the summer. Nonetheless, it is also possible that you have a different problem, especially if one of the smells you detected was "vinegar." I wonder if maybe a small animal/rodent found their way into your system and got stuck and has since expired? If the smell is only there when you first turn it on and then dissipates, then that seems a lot like a common mold growth scenario. If it persists, it is possible that you have a bigger issue.

Car AC evaporator oder is a pain to deal with. Compare it your house evaporator but its smaller and MUCH more inaccessible. It's also exposed to bigger changes in humidity and temperature than most home AC. Doing what @seo68 recommends about shutting off the AC and having only the fan blow over the wet coils to dry them out would help, but it if the mold has already had a chance to build up, its hard to get rid of. I'm curious about the star case that was mentioned by Chrysler Cares in this thread.
