Ram ProMaster City – No Blower on Speed 1 & Confusing A/C Issue

This Ram ProMaster City came in with a weird HVAC problem: no A/C and no blower on speed 1. All other blower speeds work fine, but here’s the kicker — when you turn the knob to speeds 2, 3, or 4, the A/C light turns off. Ironically, the A/C light only turns on when it’s set to speed 1 — the only speed where the blower doesn’t work. In this video, we dive into diagnosing this strange issue and figure out what’s really going on with the system. Want to support us AND get early access to the SMA videos as they are uploaded?
