I'm trying to get my G in good condition to sell, but the radiator fans (both) are not coming on which causes the engine to get hot while idling or in traffic, which has been a non-starter for most people who are interested in buying my car. It's a 2004 Sedan with 140k miles. I'm by no means an expert or even very competent when it comes to cars but here is what I have figured out so far:

1) The lower radiator hose is hot, so I don't believe it is a stuck thermostat issue.
2) I checked fuses in the box by the battery and both fan fuses have continuity
3) I checked all three relays and they are fine, but when I hooked up my multimeter to the IPDM itself and turned on the vehicle, I am not getting any voltage to the relays themselves even after the car has come up to temperature, I tested the wires at the cooling fan pigtail connection with the car in diagnostic mode and no power was getting to the fan either, which makes me think it's not an issue with the fans themselves.

How would I fix the issue of no power getting to the relays through the IPDM? Thanks in advance.
