Why is my left rear turn signal malfunctioning on my 2010 F250?
1 Answer
If it is just the one turn signal on one side that does not work. You need to check and/or replace the bulb. If it is not the bulb, check for corrosion in the socket and clean the contacts. Also check for a poor ground at the socket. If that does not work go through the trouble shooting guide at the link below: TROUBLESHOOTING BASIC TURN SIGNAL AND FLASHER PROBLEM http://www.procarcare.com/includes/content/resourcecenter/encyclopedi a/ch14/14TSTurnSignals.html
