Fans on when ignition in accessory position - ZR-1 Net Registry Forums

LGAFF · 07-04-2020

I have an issue with the fans turning on once the ignition switch is turned into the accessory position, as in supplying power, but the car is not running. I have reset the prom multiple times and even replaced the prom. disconnected the temp switch on the inj housing, and even trying jumpering the AC high pressure line switch

Thoughts, I think the only other potential issue is ECM?
