Electric brakes issue

When I plugged the power cable from my camper to my truck yesterday, I got a message on my dash that said check trailer wiring. I tested the brakes and indeed they were not working. I blew out both ends of the plug really well with my air compressor, plugged it back in, and then everything worked fine. We did have a little rain earlier in the day. This has happened a few times now. Is there anything more permanent I can do to ensure a good connection so I don't have to rely on the air compressor? Thanks.

    Keep your trailer plug in a Plug-Guard when not in use. Plug in and out several times when hooking up to wipe the contacts. Using the spray mentioned above is worthwhile.

    I see this often here on RV.net, but Dielectric grease is used for sealing, protecting and electrical insulating. Improves electrical performance by reducing arcing, voltage drop and other conditions. This will help keep out water and other contaminates.
    But it does not clean or lubricate your plugs, the cleaner mentioned earlier is what should be used first to make better contact.

    Get a small flat blade screw driver and on the trailer plug side, carefully pry the blades open a bit more so they will have a tighter fit on the trucks plug.

    Good luck! Mitch

    Cleaner is good, then put Di-Electric grease on the plug, so it covers the connection
