Hello there, Jick!
It sounds like your 2011 Ram 3500's climate control system is programmed to default to a factory preset whenever the truck is restarted. This behavior is common in vehicles with automatic climate control systems, designed to prioritize comfort and efficiency. Here’s what could be happening:
1.) Factory Default Setting: Many vehicles are programmed to default to a temperature (like 72°F) and activate the A/C for optimal cabin conditions. It’s a convenience feature, but it can’t "remember" the previous settings unless explicitly designed to do so.
2.) Battery/Memory Issue: If the system normally retains settings but isn’t doing so now, there might be a problem with the module's memory or power supply. For example, a weak auxiliary battery, a blown fuse, or a failing HVAC control module could disrupt the memory function.
3.) Software Glitch: Sometimes, the control system’s software needs to be updated. A dealership or qualified repair shop can reflash the system with the latest firmware.
Quick Fixes to Try:
You may need some parts in the process, click this link to be directed to our website where your vehicle information has already been entered. Simply enter the part's name into the search field to get started.
Best of luck getting your 3500 sorted out — here's hoping it's a quick and easy fix!

Quick Fixes to Try:
- Check the Battery: Ensure your truck's main and auxiliary batteries are in good condition.
- Inspect Fuses: Look for a blown fuse related to the HVAC or memory system.
- Settings Override: Check the owner’s manual for steps to adjust the default settings, if possible.
