Anyone ever had a problem with rust in the contacts on the fuse box?...have a issue with my blower motor, seems that the fuse plug for the radio is just above the plug for the blower motor( which happens to be the last one in the box at the bottom) and it seems that there "fused" together with rust, if I turn the fan switch on, the radio goes out and the gen light in the dash comes on... uzzled: Anyone ever have or seen anything like this??
Typically, these types of problems are due to grounding issues. It sounds to me like different components are seeking ground from other components, causing those components to act up. I would start be assuring that the installed ground straps are in good shape, and be sure that the body, frame,and engine are all properly grounded to the battery negative. This is where I suggest you start.
Update Welp, fixed the fan motor deal last night, after over a hour of tracing things down it ended up being of all things the plug for the key switch, I would have never guessed that, had one plug not making good contact and caused that to happen, just plum crazy! :spank:
While we're on the subject.....is there a way to clean the rust off of the fuse box contacts? Maybe with a mild acid...vinegar, Muriac acid??? And then, how do you keep them from rusting again? I wonder if a metal conditioner would work, like a phosphate coating.....or will that screw up the conductivity? Time to experiment!..... There must be an easier way...
The cause of the rust or corrosion is the result of the electrical activity on the contacts. In some cases, it is the result of weak connections, or plenty of current, such as the wipers or the blower. You can use catsup to clean everything up. The acid will etch the contacts, making everything clean again. Be sure to completely clean everything of the catsup, then apply a compound called bulb grease. This compound is intended to prevent corrosion caused by the elements described. Since it will not act as an insulator, use enough to completely cover the contact area. Let us know...
