Rundown: bought 97 f150 truck with no working 4wd, just bought and installed used number and letters matching gem and still doesn't work. Symptoms are start truck or turn key on, put in 4wd, part next to tach clicks about five times and nothing happens. It will click again if i cycle key back off but only one set of five clicks each key cycling. Pulled transfer case acutuator motor and tried it and motor does not move. Any help would be great on how to further test have meter just need direction..
