Error cf after water getting in (foged lcd and viewfinder)

I was on the road taking shots and suddenly started pouring really bad. Got home camera was soaked, humidity started forming inside the viewfinder and the top lcd. Removed alla batteries and the cf card and let it dry on a radiator. It was still working at that point but in the nexr morning after it had dried up it was acting all crazy back lcd wouldn't turn on etc. So I let it dry more currently it is fully functional until I get a cf card inside. As long as I do that it looks like it's freezing for a few seconds and then says cf err on the top lcd and the shutter won't fire. Tried multiple cfs formated them etc still the same. No bent pins or anything. So should I replace the whole cf slot? Is it a pcd that reads the cf slot that may have short circuited? Any tips would be much appreciated!!
