My son installed the Thermostat last night. The only way we could get it to work was to put the G wire into the C spot and then go into the attic and put that G wire onto the C spot. Now it turns on. Both heat and A/C. But there is no fan blowing air from the ducts. Can someone help me? This is the video we watched. https://youtu.be/zzMuTqT7SRg.
Also, there is a blue wire at the thermostat that is not hooked to anything. It is not stripped. Is this the wire that Should actually go into the C spot?
I hope this makes sense. I really have no idea what I’m doing so any advise would be well received.
