On the 2007 Kia Spectra, the A/C blower speed switch and resistor pack are wired on the ground (negative) side of the circuit. That’s typical for a lot of Kias and Hyundais from that era.
Here’s a basic sketch-style layout to show how the blower motor circuit works in this vehicle. It’s a bit simplified, but it gives you a clear picture of how the current flows:
[+12V Battery/Fuse]

|
(Relay)
|
|
[Blower Motor]
|
|
-------------------------------
| | | |
[Low] [Med] [High] [Full/Bypass]
Resistor Resistor Resistor (Direct Ground)
| | | |
-------------[Blower Switch]------------
|
[Chassis Ground]
But of course, that's just a simplified representation of the system. If you want to troubleshoot the system, test components, or even verify specific issues like faulty switches or resistors, you’ll need the connector locations, wire colors, and other critical details. For accurate diagnostics, you’d want to refer to the complete troubleshooting chart included in the official repair manual for this vehicle. Having the manual will give you all the information needed to properly diagnose and fix the issue.
