Pontiac Laurentian Turn Signal Switch Connectors

Pontiac Laurentian Turn signal switch connectors

Starting at low prices, AutoBuffy stocks multiple turn signal switch connectors from top OE-quality brands for the Pontiac Laurentian. This connector is the wiring harness plug that links the turn signal switch to the vehicle's electrical system — when it corrodes, cracks, or loses a terminal, signals may stop working entirely, creating a safety and legal hazard on every drive.

Signs your Pontiac Laurentian needs a new turn signal switch connector

  • Turn signals on one or both sides flash erratically or not at all despite a good bulb and fuse
  • Hazard lights work but turn signals do not, pointing to a connector-level fault rather than the switch itself
  • Visible burn marks, melted plastic, or green corrosion on the connector body or terminals
  • Turn signal function returns temporarily when you wiggle the steering column wiring harness
  • OBD scanner or body control module stores a turn signal circuit open or short fault code
  • Interior dash indicator light for the turn signal stays on constantly or does not illuminate at all

Which turn signal switch connector should you buy for your Pontiac Laurentian?

The most important decision is whether to buy an OEM-spec connector with pre-loaded terminals or a bare connector shell you re-pin yourself. Your choice depends on how many terminals are damaged and whether you want a plug-and-play repair or a cost-saving rebuild. Confirm the exact pin count and connector family before ordering, as several connector generations may cover the all model years production run.

OEM-spec pigtail assembly (pre-terminated)
Best for
Fastest, most reliable repair with no splicing skill required
What you get
Connector shell, pre-installed terminals, and 6–12 in. of color-coded lead wire ready to splice
Bare connector shell (re-pin kit)
Best for
Replacing a cracked or melted housing when original terminals are still good
What you get
Shell and locking clips only — you transfer or source your own terminals
Terminal repair kit (individual pins)
Best for
Fixing one or two backed-out or corroded pins inside an otherwise intact connector
What you get
Correct OEM-gauge terminals, seal plugs, and extraction tool for the connector family
Complete clock-spring / column harness section
Best for
Extensive wiring damage across multiple connectors in the steering column area
What you get
Longer harness segment covering the turn signal connector and adjacent plugs for a comprehensive repair

Replacing a turn signal switch connector on a Pontiac Laurentian

Moderate⏱ 45 minutes – 2 hoursTerminal pick or removal tool setWire stripper and crimping tool (or soldering iron and heat-shrink tubing)Multimeter for circuit verificationTrim panel removal pry toolsElectrical contact cleaner and dielectric grease

The steering column lower shroud must be removed to access the turn signal switch wiring on most Pontiac Laurentian applications, so budget extra time if this is your first column disassembly. With the battery disconnected, unplug the damaged connector, splice or re-pin the new pigtail using solder-and-heat-shrink or ratcheting crimp terminals, then reconnect the battery and verify all signal functions before reassembling the column shrouds.

Frequently asked questions

How much does it cost to replace turn signal switch connectors on a Pontiac Laurentian?
The part itself starts at low prices at AutoBuffy. A pre-terminated pigtail you splice in yourself is a straightforward DIY job, so labor cost can be near zero. A shop may charge one to two hours of electrical diagnostic and repair time on top of the part price if the fault was difficult to isolate.
Can a bad turn signal switch connector cause the hazard lights to stop working on a Pontiac Laurentian?
Yes, but it depends on pin location. Hazard and turn signal circuits often share the same connector housing on the Pontiac Laurentian. A shorted or open terminal in a shared pin will kill both functions, while a fault in a turn-signal-only pin typically leaves hazards intact. Check which pins are affected before replacing the full switch.
Is it safe to drive my Pontiac Laurentian with a faulty turn signal switch connector?
No. Non-functioning turn signals are a traffic safety hazard and an equipment violation in every U.S. state. Other drivers cannot anticipate your lane changes or turns. A melted or shorted connector also poses a fire risk inside the steering column. Repair it before returning the vehicle to regular road use.
Can I repair the connector instead of replacing it on a Pontiac Laurentian?
Often yes. If the shell is intact and only one or two terminals are corroded or backed out, a terminal repair kit costs less than a full pigtail and restores a solid electrical connection. Replace the entire connector if the housing is cracked, heat-damaged, or if multiple terminals are compromised, since a partial repair may fail again quickly.
How do I know if the problem is the connector or the turn signal switch itself on a Pontiac Laurentian?
Unplug the connector, clean the terminals, and measure voltage at the harness side with a multimeter while an assistant activates the turn signal stalk. Correct voltage present at the harness pins points to a bad switch; missing voltage with a good fuse points to a wiring or connector fault. This test takes roughly ten minutes and avoids buying the wrong part.
Will any generic connector work, or does it need to match exactly for the Pontiac Laurentian?
It must match exactly. The connector on the Pontiac Laurentian is keyed to a specific pin count, terminal gauge, connector family, and locking tab style. A generic plug may fit loosely, carry inadequate current, or lack weatherproofing, causing intermittent faults. Always cross-reference by connector family number or use a confirmed fitment listing for the all model years Pontiac Laurentian.
