No rear drivers side I have no tail lights nor signal light. Bulbs appear to be good. 4 ways flashers work ok as do brake lights. I checked the internet looking for the flasher and found comments that indicate the 2008 Ford Explorer does not have a flasher and that signal light flashing is controlled by a Junction Smart Box .. Is this a sealed unit or can I buy some part to repair my signal lights so they flash properly . Everything works on the rear passenger side as well as the front of the vehicle

If fuse 10 in the fuse box is good, which I assume it is or you would have other functions not working then the problem may be the combination flasher module or the multifunction switch, the flasher is the cheaper of the 2 parts ($12) so I would try it first, you might be asking why would this cause the problem when the 4 ways work, well like I said it is a solid state unit and operates both the flashers and 4 ways independent of each other, if that is not it then the problem is the turn signal switch.

with the blinker on hold the socket in your hand and wiggle on the bulb and see if it starts to blink. if so then you have a bad socket that needs replaced or sometimes can be cleaned and apply electrical grease. if you cant get the bulb to blink then get in vehicle and watch the signl indacator while putting pressure on the selector in which ever direction your having problems with. if you get it to work properly by doing this then you will need a new switch .

Just found the answer on another site. Sure enough went out removed the 3 philips head screws in the steering column opened it up and walla a wire connection had pulled itself free. When my son uses my truck he always uses the tilt steering, when I get in I have to readjust it. because of this the wire connection pulled itself out. I simply pushed it back in an blinker and brake light are now working. My husband is now trying to figure a way to secure the wire connection so it doesn't pull itself out again. Hope this helps others, either by saving the cost of a dealership or machanic or from getting rear ended.

It doesn't actually have one this function is incorporated into the smart junction box.
The SJB monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is pressed, that input signal is routed to ground.
When the SJB receives a request for a turn signal or the hazard lamps, the SJB supplies on/off voltage to the appropriate turn lamps.
The timed on/off cycle is determined by the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If an individual turn signal lamp is inoperative, the SJB fast flashes the remaining turn lamp approximately 160 times per minute to indicate to the driver of a bulb outage.
The SJB bulb outage is configurable and can be turned off for the rear lamps. This is to accommodate vehicles that have been upfitted with rear LED lamps in place of the traditional incandescent bulbs.
