GMC SIERRA CHECK ENGINE LIGHT PROBLEM

2006 GMC Sierra • 108,000 miles

I am having problems with the cooling fan relays. My check engine light is on and when I had it checked it said there was a problem with the relays, I have replaced a fan motor and all three relays and still to no avail the fans will not come on. What should I check next?

Check to see if there is power at the relay.
