If your RX-8 only blows cold air no matter what you set the dial to—or worse, it only pumps out heat—you’re likely dealing with a common failure inside the HVAC control unit.
Rather than spending $240–$350+ on a replacement (or risking another failure with a used one), we offer a reliable, bench-tested repair service that targets the root issue: faulty solder joints on the control board.
🔧 Common Symptoms:
Blows only cold or only hot, regardless of setting
Temperature dial or buttons seem unresponsive
Heating/cooling cuts out intermittently
No changes in vent temperature even after the system cycles
We remove, inspect, and professionally reflow the circuit board to fix the underlying issue and extend the life of your factory unit.
