Are you sure bulbs are good ?? double check bulbs also make sure there is a ground wire from your light fixture is grounded to the body near by this might be causing your problem .. usually if front ones blink fast rear bulbs are bad ... thanks Jerry holler if you need more.

Hello There ,
I will Try my best to Walk you through this , Ok We Need to Know If ALL that's Not Working In the rear is Turn Signals? You need a Helper to look 1.First for Tail Lights 2. Next BRAKE Lights apply Brakes and have Helper see.
This Points to A BAD GROUND in A CAR This is Usually In the Trunk Fallow Wires FROM TAIL LIGHT Assembly and Look for Anything Out of Ordinary with Wires such as Corrosion Anywhere Clean and REPLACE Section of wire if Nessesary. On GM Vehicles there Is A GROUND WIRE SCREWED or BOLTED to Trunk FLOOR or SIDE RAILS We Must RULE OUT BAD GROUND. After this Comes the Parts CO$T.This May Very well Stop Here and FixYa. If Not we make sure FRONTS are Working. Bad Ground in the Trunk happens a lot Especialy When we Carry A Lot Of Things in the trunk. LOOK UNDER TRUNK LINER and BEHIND CARDBOARD SIDE Covers. Is there a Trailer Hitch & plug if so liminate the Trailer Plug Wires as the Problem. We would Rather WASTE a Little time At a Chance of SAVING MONEY Than WAIST MONEY Now AFTER a FULL Inspection. the Problem May be Found and Repaired at this Point, if so Good if Not Problem is Most Likley The Turn Signal Switch itself or Multifunction Switch
SIR CAUTION You Must Disconnect Battery Terminals + & - While Replacing this Switch

Kia turn signal works but blinks fast on right side when parking lights are on

turn on park lights and signal on right side and take a good look at the front and rear light , see if one is dimmer than the other this may be due to a bad ground and when the park lights are on and drawing more power it also needs better ground, check the sockets front and rear try wiggling the bulb to see which one is causing the problem

Front left turn signal blinking fast

If the front signal is blinking fast then theres a bulb out, check the rear to see if theres a bulb out, use the right side to see how many light are blinking and make sure the same is on the left, the main reason for fast blinking signal is a bulb is out on that side. good luck, have a nice day.

no it can not be the flasher. if bulbs and socket is good in left rear u may have no power or ground. need to check wiring to that lamp. also fast blinking is a normal condition when you have a lamp out
