I am having troubles with my main radiator fan. The sub fan works just fine. I did not have my multimeter until today, so I brought power directly to the main fan to check it and it did not come on assuming this was the issue I replaced the fan, and it still does not work..I then used my multimeter to for power at the fuse box under the hood, no power. the sub fan relay has power and I confirmed this with my meter. Any suggestions or thoughts would be helpful and appreciated.
