No cold water, shower only, any plumbers?
I already replaced the moen valve assembly, I cleaned out the pipe, nothing seemed to be in the way. Note: its never been this cold here since I have been alive? Could the shower pipes be ran separately from the bathroom sink, seems unconventional to me, house was built in 84 and maybe the shower pipes are just closer to the outside wall. There is a protruding wall in the garage, I might put a camera snake in there to see what I am dealing with.
You cannot see or trace the pipes in the basement, they just go up through the ceiling, I checked under the kitchen and bathroom sink, cant see anything, not sure where the pipes are ran.
