Hey guys I have a 99 f250. I have warn manual locking hubs because I didn't like the vacuum idea so that isn't an issue however I have the electronic switch and my 4wd will not engage. When I switch it on I am getting no light on dash however when I turn my key on before it starts the 4x4 light flickers so the light does work. Any ideas? I replaced the relays so that issue is ruled out. Thanks guys!
