Thanks for all the great help. NOT

 

I will reply, just because this post was recent-ish & has no reply. Hi! I hope you fixed your issue. I am having the same issue. Unfortunately I can be of no assistance whatsoever, aside from moral support and the occasional comedic relief. So, everything worked fine, I had just recharged the a/c & it was cold!! Then I had to replace a coupler in the steering wheel. Once I got it back together, the a/c and heat, the controls for those nor the lights on any of it. I checked and replaced all the fuses before and after the issue, not a fuse in the inside panel. The blower comes on, but doesn't blow. The rear defrost works. I should also mention, when I say "I" did these things- I actually mean my ex did them. Its his car, which he was going to buy for me. Then, I ended the relationship, and if you ask him, that's why I do not have a Soul. So, now I'm riding passenger, it's getting cold out, and there's no heat, or front defrost. Hope you get better help, or that you figured out the issue and can help me to save my Soul from the cold. Good luck to us both & Thanks!!

Here's what my AI friend says:

Ok, that’s a different failure pattern — and your clue is “after working on the steering wheel.”

That immediately points to something disturbed in the dash wiring, not a blower or resistor problem. Let’s break it down:

Symptoms

• A/C and heater controls dead (no lights, no function).
• Blower motor spins but no airflow (so the blend doors/flaps aren’t moving).
• Rear defrost still works (that’s on a separate circuit).
• Problem started right after steering wheel coupler replacement.

Likely causes

• Disconnected HVAC control harness.
  • When the steering wheel area was apart, the lower dash or center panel wiring may have been pulled loose.
  • The HVAC control unit has a single multi-pin plug behind the control face — if that’s unplugged or half-seated, the controls and lights will all be dead, and the blend doors stay shut → blower runs but no air.
• Ground G05 / G07 loose or disturbed.
  • There’s a shared dash ground near the steering column bracket. If that wasn’t reattached after steering work, anything using that ground (HVAC controls, illumination, etc.) dies.
• Short or damage in the steering-column harness.
  • Clock spring / coupler work can pinch or break the harness feeding the control panel illumination circuit.

What to do

• Pull the HVAC control panel (it just pops out with trim tools).
  • Check that the main connector is firmly seated and not bent pins.
• Check grounds on the left dash frame near the steering column.
• If connector’s fine, check for 12 V on the HVAC panel feed (usually pink/black wire) with key ON and fuse #15 (or similar) good.

Bottom line:
✅ Blower runs = power path intact.
❌ Controls dead after steering work = unplugged or grounded HVAC control harness — 99% likely.

Plug it back in and everything should wake up.

 

My AI friend again:

The situation

• You have power at the relay input (battery feed) — good.
• No power to the relay control (coil) — that’s the key clue.
• That coil circuit is controlled by the blower switch circuit, which gets power from the ignition switch (and possibly the blower resistor or control module, depending on if it’s manual or auto climate).

Common causes on 2013 Soul:

1. Blower motor resistor/module failed (very common).
   • The control side of the relay runs through the resistor pack or control module in many Souls.
   • If the resistor opens up, it breaks the relay trigger path → no relay click → no power to blower.

• • Test: Unplug the blower resistor (under dash, near blower motor) and check for 12 V on the feed wire with key ON and blower switch at HIGH. If no power, move upstream.
• Failed blower switch (HVAC control head).
  • The switch completes the ground or power path for the relay coil.
  • If it’s open, relay won’t energize.
• Ignition switch output fault.
  • The blower circuit usually gets its control power from the “IGN2” circuit of the ignition switch.
  • If IGN2 is dead, blower, rear defrost, or wipers may all be out.
• Broken wire or poor connector in the relay socket or resistor harness.
  • Souls are known for melting or corroded blower resistor connectors.

Quick check sequence:

1. Key ON, blower switch HIGH:
   • Does the blower relay click?
     • No → check for power and ground at relay coil terminals.
2. If coil has no power → trace back to ignition feed or switch.
3. If coil has power but no ground → check blower switch or resistor ground path.
4. Jump power directly to blower motor briefly → confirm motor itself works.
