Air conditioning issues 2015 ProStar

[Kritter47]

Got a 2015 ProStar that blows cold air when idleing but blows hot air when going down the road. Also can’t seem to locate the thermisters on the truck.

RE: A/C Cooling Issue
The truck makers, they know the A/C systems are going to be a money maker for them. They are designed to do nothing but act up and run like a P.O.S. all the time. - They are designed to be nothing but problematic in these newer trucks.

-- I got totally sick of it a long time ago on my own truck and solved it.

I no longer suffer Air conditioning issues. I solved all of my trucks A/C problems with an Arduino ... Works like a charm.

Here is some more info related to the A/C and a link to that arduino project that I did as well ... http://rawze.com/forums/showthread.php?t...7#pid14467

it's a little circuit board you can program commands into using a C++ program.

replacing the thermisters is likely the fix.


post an overview pic of the passenger side of your truck up by the firewall where the big black plastic A/C box is. That is where the thermisters will likely be.

here are where mine are located...



A person needs to bleed the system to zero before attempting to remove them.

i thoguht they were just sealed up and covered over with heat shrink tubing on the newer ones ... but i may be wrong.

(why i requested a couple pics of what they actually have).
