I had the same issue and this is what I did to fix it. Was going to be $400 to get a new wire ran without the drywall work. I ended up just getting a nicer big fan/light for $150 and replacing it myself.

How old is this? My hot water valve got stuck/old so I started replacing the valves. Center valve came out no problem. Hot water one wouldn’t budge no matter what. Called a plumber and turns out it was original to the house and the valve was pressed in. Only way to replace was to force it out and press in a new one.
I opted to replace the entire valve setup by busting a hole through the opposite wall.
