The Fans stopped working in the car randomly after some work done to speakers/audio/radio. They stopped a good 1-2 weeks after all work was done, so possibly completely unrelated. Initially ALL fuses were checked and none were blown, suspicious went to a dead blower motor because the AC turned on and it spun but just the air wasn’t blowing. Motor was replaced with a brand new one, and it still won’t spin. This leave in question the Climate Control Module. Is this part intelligent? No fan speed or direction will work and blow air. The piece has several plugs into it. Do you think replacing this module will solve the issue? Im thinking it may be that the blower motor is just not receiving a “on” signal.
Worth noting that days prior half the LEDs on one dial turned off, then came back after a few days, and when its not working right now, the LEDs do come on and things like the AC on light do illuminate.
As always, any help figuring out this issue is greatly appreciated.

Stop firing the parts cannon. Need to know some EXACT info about your car
for starters: Engine Size, Auto or Manual transmission for the rest look at my signature.
Also Auto or Manual climate control?

Its not firing the parts cannon, Im going over all the parts i’ve already checked/replaced and the ones that are remaining, which is important in troubleshooting the issue to anyone else trying to solve.
It is the Manual climate control. Its a V6 automatic, although that doesn’t really have any pertinence to the fans not turning on? The Model should be the 300 (not the M).
Sorry if I came off as rude, that wasn’t my intention. I have access to Mitchell ProDemand and can pull your wiring diagram to answer your question provided I know the displacement of your engine (often called the engine size) i.e. 1.6L , 2.0L, etc. In your case the options are:
2.7 L, 3.5L, 5.7L, 6.1LI’m going to guess that you have the 2.7L and go from there, if you need to know where to find your engine size look on your VECI (Vehicle Emissions Control Information) label under the hood-should be whiteish and plainly visible by law.
I strongly suspect that your prior fan was perfectly fine and the blower motor resistor/transistor has either cooked itself with age (which happens) or whoever did your radio/audio work either left something unplugged or inadvertently shorted the resistor. Attached are the Theory, Operation, and Testing instructions for you on further troubleshooting. Follow them and get back to me please.

Thank you, the car is the 2.7L model. I did not know you could look up something like that with the info on the engine, so thats something for me to learn for future questions. That PDF you linked is very helpful. It’s a friends car im helping work on. I can figure out mechanical stuff ok and solve, but im definitely learning when it comes to a cars electrical system. Next chance I get I will take apart the blower motor resistor and attempt to check for continuity. I actually did the audio work myself, all connectors are definitely back in place and I soldered back and wires I wired up, not just a twist and crimp.
Usually just a quick visual check of the resistor should suffice, shorted or blown coils on one aren’t uncommon with age-no matter what vehicle they eventually give out-part of the reason why manufacturers switched to some form of integrated PCB (plastic circuit board)-based relays instead of a separate removable one.
If you have a Power Probe or fused jumper wires simply unplug the blower motor from the resistor and apply 12v power to the power wire (indicated in the diagram)-if the blower fan now runs (should be on “high”) the resistor is the issue.
