Great info!!! Thanks for doing this and posting the results.
The next question is if anyone has gotten temps as low as your closed valve temps without adding a valve. If so then the question is why.
Excellent video @thestuarts thanks for doing this work.
Hey @RamCares this is something you need to take note of and report up the chain...
Ya its an opinion issue, however Dodge Ram AC has never been a meat locker.I think it is one of those personal opinion things. I’m from SW Kentucky. We see our upper 90s days with 90 percent humidity for feels like temps of 105 plus in the summer. My truck is black as well. I have not had a problem with my AC. Have I had better A/c or heat in other cars? Sure but I can’t say the AC in my Ram is bad, I stay comfortable and cool all summer long. I had never even gave my AC a rating or thought about it until I read on the forum, all the complaints. Then I wondered was there something wrong.
I lived in SaCal for most of my life, and for those that think its dry heat, think again when the thunder heads roll over the mountains and the humidity goes over 80% at 110* most auto AC's wont keep up when just getting in the vehicle.Humidity? What's that? I just meant it seems to keep up in absolute terms, there were a bunch of posts about problems keeping up even in dry climates like CA & AZ.
Hey I checked my vent temps with AC on high speed fan at beginning. I used Snapon thermal imager and it measured 38-39 flowing out of all vents and that was 10 - 15 minutes driving then idling for 5 minutes. The temps increased to 48-52 degrees after 30 minutes. Now this is why I think it’s another issue than blend doors.I’ve worked in the automotive field for 20 years and I’ve never seen numbers that low. I’d check your equipment and there’s always a difference from one side to another.
Hey yes it needs to be on high speed fan to get it to keep just cool not cold. I just read someone who had TSB blend doors done on his 2019 and it didn’t make any difference. I still believe it’s a door motor , cycling or Freon issues. Maybe reset like another member indicates.If I put my fan speed on any speed lower than 5 on a hot day, it is pointless. Once the cab is cooled down, I can sometimes lower it to 4. To me the fan speed has too much of a percentage increase/drop between speeds. Also, my defroster leaks air by, the windshield condenses in the mornings and I can feel the air coming out. It's not much air but enough.
How do I reset and what am I resetting? Calibrating the blend doors?Hey yes it needs to be on high speed fan to get it to keep just cool not cold.
