I recently wired in a new ceiling fan and first it was on constantly no matter if switch was on or off then rewired and lost all power to back two bed rooms only no breakers are tripped main or secondary

How about removing the fan and tell us what the wiring in the ceiling box looks like.

No wires are burnt in the receptacle or fixture

Not what I meant. Describe the number of wires/cables in the ceiling box. Number/color/connections.

White to white
Green to bare ground
Black to black
Red to black

In the ceiling box there is probably three cables. There is probably two cables with a black and a white wire and one cable with a black, a red and a white wire. Or there might just be two cables, one with a black and a white wire and one with a black, a red and a white wire. Can you describe what's there like that?
A wire is a wire. A cable is two or more wires in an outer covering.

Power to my garage is out how do I fix it
