fuse block on 1992 Chevrolet G Series Van (G20)

My fuse block is getting wet i need to rewire it. I need all the info i can get on this. Please someone help.

Is this the under hood fuse box - near the left side fender? If so you could be missing a water deflector to protect the fuse box. Depending on the amount of damage you may need to replace the fuse box. The connectors which plug into the fuse box may also be damaged. Any that show signs of corrosion will need to be replaced. This can be a very complicated repair. You may need some help with this one!
I think you should take a close look at your fuse box and the connectors plugged into it and the wiring around it. You will need to replace whatever looks to be damaged from the water. Look for corrosion in the connectors that plug into the fuse box. You may need to unbolt the fuse box as there may be some connections in the back.
thank you for your answer. This one is inside the van. We think we found the leak. Should i get a new fuse block to start out with?
