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
So as to Not Accedentaly DEPLOY AIRBAG WHILE Performing this Repair
Multifunction, Turn Signal Switch Replacement
Caution: Refer to SIR Caution in Service Precautions.
Important: The electrical contact on the turn signal and multifunction switch assembly must rest on the turn signal cancel cam assembly.
6. Install the turn signal and multifunction switch assembly. Notice: Refer to Fastener Notice in Service Precautions
