An A/C control module that doesn't power on could have an external circuit issue or an internal failure. Properly diagnosing this issue is done by checking both the the power and ground circuits for the module. Looking at a wiring for the 2005 Kia Spectra, I can see that there are two power supply circuits. The first is a blue wire (pin #1 in the module connector) which receives power from the "A/CON" fuse (10A) located in the instrument panel fuse box. This circuit is the main power supply for energizing the unit. The second is a pink wire (pin #2 in the module connector) which receives power from the "ROOM" fuse (15A) also located in the instrument panel fuse box. This circuit is the power supply for the unit's memory (used for retaining settings). Lastly, the ground circuit is a black wire (pin #11 in the module connector) which provides a ground path at location "G4" below the center of the dash. If all circuits are OK, the control unit has likely failed internally. You can read more here: https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-ac-control-module
The Transmission Control Module is located inside the transmission at the rear of the case underneath the end cover. The Transmission Control Module is located in an E-Box in the plenum chamber on the driver-s side below the Engine Control Module (ECM).

System Description EKS0058X Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.When the lighting switch is placed in the fog lamp position the BCM (body control module) receives input signal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the front fog lamp relay coil. When activated, this relay directs power to the front fog lamps. OUTLINE Power is supplied at all times ? through 15A fuse [No. 43, located in the IPDM E/R (intelligent power distribution module engine room)] ? to front fog lamp relay, located in the IPDM E/R (intelligent power distribution module engine room) ? through 15A fuse [No. 34, located in the IPDM E/R (intelligent power distribution module engine room)] ? to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room). Power is also supplied at all times ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM (body control module) terminal 55 ? through 10A fuse [No. 21, located in the fuse block (J/B)] ? to BCM (body control module) terminal 42. When the ignition switch is in ON or START position, power is supplied ? to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room) ? through 10A fuse [No. 1 located in the fuse block (J/B)] ? to BCM (body control module) terminal 38.

System Description EKS005BP Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/ R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays, when energized, direct power to the respective headlamps, which then illuminate. If voltage is applied to a high beam solenoid, the bulb shade will move and a high beam and a low beam are changed. OUTLINE Power is supplied at all times ? to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room), and ? through 15A fuse [No. 34 located in the IPDM E/R (intelligent power distribution module engine room)] ? to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room) ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM (body control module) terminal 55 ? through 10A fuse [No. 21 located in the IPDM E/R (intelligent power distribution module engine room)] ? to BCM (body control module) terminal 42 ? through 10A fuse [No. 19, located in the fuse block (J/B)] ? to combination meter terminal 24. With the ignition switch in the ON or START position, power is supplied ? to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room)
Ford is fond of placing the power control relay in the under hood fusebox, but there may be a larger problem with the ABS control module which is located on the inside of the driver side frame rail - usually just behind the driver seat.There are some models that have the relay mounted next to the control module.
Hope this helped!!
tragik nc: In looking this car up in both the 4 and 6 cyl configurations, Ford said that the ignition control module is no longer a separate component. It is actually integrated into the PCM (power control module)
This is located in the right rear corner of the engine compartment behind the power steering reservoir.
Good Luck, mybunkey>>>>>>>>>>>>>>>>>
