[QUOTE="mwolson, post: 14973814, member: 16006"] I am confused by your description. There are 4 turn signal bulbs on each side, one at the front, one in the instrument cluster and two in the rear. It is not clear from your description which bulb or bulbs are not working. Since the bulb in the cluster is working, you know the multifunction switch and flasher are working. On the right side, there is a Orange/Light Blue wire that runs from the multifunction switch to all of the bulbs. You can turn on the right turn signal and check the center pin inside of the bulb socket for the front and both of the rear sockets for intermittent battery voltage with a voltmeter connected to a known good ground. If you don't see intermittent battery voltage on the center pins, you have a break in the signal wire. You can use an ohmmeter to check the resistance of the side of each socket to a known good ground. It should be very close to 0 ohms. If any of them have infinite or large resistance, check for broken wires and bad grounds. All 4 of the rear turn signal bulbs are grounded to one point at the back of the car somewhere. Each front bulb is grounded to a different ground point somewhere in its side. The park lights all use the same ground points, so if they are working, the problem isn't the ground wires or corrosion at the ground point. The only other thing I can think of is that the springs inside of the socket have failed and are not pressing the center connector pins to the bulb. [/QUOTE]
