I'm trying to upgrade the bathroom exhaust fans in my house because they're really loud and outdated. The problem is, my master bathroom doesn't have a fan above the shower, just a regular light. When I checked the attic to locate the wires for the light, I couldn't find them, and I noticed that the ceiling above the shower is slightly dropped. There's also a wire in the drywall that could be from the light. The attic is packed with insulation, so I'm wondering if there's a clean way to access the dropped ceiling without making a huge mess, or if I should just cut a hole in the drop ceiling from the attic. The house was built in 2004, so does that make a difference?

I had a similar situation and wired my new fan directly next to the light. There was already exhaust venting from another bathroom, so I just connected it to that. When the bathroom light is switched on, it also powers the exhaust fan. It’s a great way to keep moisture out without needing a separate switch.
From what you’re describing, it sounds like the insulation might be filling in around a framed box. You should be able to reach the area from the attic. Upgrading to a light and vent combo could work, but keep in mind that the shower may get cold due to the fan pulling steam out. Have you thought about adding a vent in a different spot in the bathroom instead? Also, consider how humid your bathroom gets; is it prone to mold? It's usually pretty straightforward to swap out the light, but if you go the fan route, just remember you definitely don’t want to vent to the attic—it could cause some big issues! I did a vent installation in my place, and it involved cutting a hole, removing insulation, and running a line from the switch.
You’ll need to cut into the upper ceiling for ducting and also the lower ceiling for the fan itself. Before you cut anything, turn off the power, remove the light, and try using a coat hanger or similar tool to help locate where that wire goes up in the attic. Just remember to move insulation away from the area before you make any cuts, and then recover it afterward.
Just a reminder: when you install that fan, make sure it's vented outside properly! I’d recommend checking out the layout before you make any cuts to avoid complications.
