It is actually pretty easy...I too thought it might be difficult. There is only one screw to remove.It is located on the outer edge of the lense. Remove the screw and easily pry out that same corner...the whole lens will come right out. I just recently did mine. ...now I have to replace the starter!!!
Town and country vans have never had speedometer cables. The speedometer gets it's signal from the transmission computer.
Either hand signal or check and replace your fuses and turn signal bulbs.
For the front or rear turn signal?
It's the turn signal indicator-located behind the hazard lights.You have to take it out and replace it.
You should follow the Youtube instructions.
Open the rear hatch of your van. There are two black button like protrusions behind the hatch next to the turn signal lamp. Pry these out and remove lens. Replace bulb.
Replace the turn signal flasher relay.
Most of the cars now have composite lights and the lights have to be revomed to replace the bulbs.
You may have a weak or blown flasher unit.
Look for either a blown fuse or replace flasher unit for the signal lights (it is separate from the hazard lights flasher unit).
the multifunction switch... ( turn signal) twist it to turn on the lights and once the lights are on pull it towards the door to turn the fog lights on
