        Pull the plug to the fan and check for resistance (ohms) toward the fan. If the resistance is within spec (prob 15-25 ohms, buy you will need to verify specs), check for power. If no power, you will need to look at the relay that feeds that circuit. Did it stop working after work was done?

          If it’s not working in active self test or the IPDM E/R test, that will do low and high speeds. The Z has 3 relays that control the two fans. Two 40amp fuses. Check fuses, swap relays. If no change, maybe wireing or maybe bad fan. Can also check cooling fan operation when you turn the A/C on.
