As the title says. I've got a 95 ford e350. Brake fluid got on one of the relays and caused a short. I need to remove the power distribution box to try and fix it but can't locate any visible fasteners

 

After you disconnect one of the battery cables from the battery (Negative preferred)
Since brake fluid is alcohol based,, could you remove the one or two relays affected and just dump a little rubbing alcohol over the area with brake fluid contamination?
If done carefully , it should all evaporate pretty quickly. You just need to be careful and don't try to give the whole assy a bath. Given a while to evaporate just clean off the relays and reinstall them. Would be good if you had a way to blow dry the alcohol faster with compressed air, Sometimes a shop vac connected to the output side connection will work too. Meaning NOT vacuuming , but blowing air out.

 

thanks for the reply. Unfortunately it sat on there for awhile and ate through underneath

 

Thanks for the reply. As you can see from the picture it had been sitting on there and ate through underneath the relay.
