headlights??

my headlight switch is going bad . when i turn them on i usually just get parking lights unless i wiggle around the bright/ blinker arm usually by pulling it towards me theyll come on and after a coupleattemps i can get them to stay any idea whats going on here. if its just the switch how hard is it to fix

*sigh* If you look back, or use search, this topic has been covered many times. It's not the switch, it's the connector going to the fuse box under the dash. It's the connector with all green wires. Unplug it and see if it has burn marks on it.
