Hi I have an aem ems that is controlling my radiator fans. When temp is above the threshold 180 the radiator fans are suppose to turn on. The only fan that turns on is the radiator fan. When temp is above 180 and I turn the ac on the ac fan still don't turn on. I have spal fans. I have checked the fans to make sure they work and they are working. California is starting to get hot, when I'm at a stop or traffic my temps could go up to 220+. I was thinking i could splice the ac fan into the radiator fan. Would that turn on the fan if I use ac though? If you could point me in the right direction on what to check next or things I could do that would be great.
