Plymouth Gran Fury Brake Light Switchs

Plymouth Gran Fury Brake light switchs

Starting at low prices, AutoBuffy stocks multiple brake light switches from top OE-quality brands to fit your Plymouth Gran Fury. The brake light switch mounts near the brake pedal and signals the brake lights to illuminate when you press the pedal. A failed switch leaves drivers behind you without warning, creates a safety hazard, and can disable cruise control or prevent the vehicle from shifting out of park.

Signs your Plymouth Gran Fury needs a new brake light switch

  • Brake lights stay on constantly even when your foot is off the pedal
  • Brake lights do not illuminate at all when you press the pedal
  • Cruise control disengages randomly or refuses to engage
  • Automatic transmission is stuck in park and will not shift out
  • A brake warning light or check engine light appears on the dashboard
  • Brake light behavior is intermittent — working sometimes but not others

Which brake light switch should you buy for your Plymouth Gran Fury?

Most Plymouth Gran Fury owners have one real choice to make: OE-equivalent replacement or an upgraded heavy-duty unit. Fit matters most — the switch must match your pedal assembly bracket and connector plug exactly, or it will not seat or signal correctly.

OE-Equivalent (Single-function)
Best for
Most daily drivers needing a straightforward fix
What you get
Matches factory specs for lighting signal only; plug-and-play fit
OE-Equivalent (Dual/Multi-function)
Best for
Vehicles where the switch also controls cruise control, shift interlock, or ABS
What you get
Single switch handles multiple circuits; critical to match original connector
Heavy-Duty / Extended-Life
Best for
High-mileage vehicles or fleet use with frequent brake cycling
What you get
Reinforced contacts rated for more activations; reduces repeat replacement
Adjustable Switch
Best for
DIY installers fine-tuning pedal engagement point after pedal or master cylinder work

Disconnect the battery negative terminal, then locate the brake light switch above the brake pedal under the dash — it contacts the pedal arm when released. Unplug the electrical connector, release the locking tab or loosen the retaining nut, and swap in the new switch. Reconnect the connector, restore battery power, and verify brake light operation and cruise control function before driving.

Frequently asked questions

How much does it cost to replace brake light switches on a Plymouth Gran Fury?
The part itself starts at low prices on AutoBuffy. Because the brake light switch is typically a clip-in or single-bolt mount located right at the pedal, many owners replace it themselves in under 30 minutes. Shop labor, if needed, is usually less than one hour of shop rate, keeping total cost low.
Can I drive my Plymouth Gran Fury with a bad brake light switch?
Technically the vehicle will move, but you should not drive it. Non-functioning brake lights are illegal in every state and create a serious rear-collision risk. A switch stuck in the 'on' position drains your battery and can cause brake drag on some systems. Replace it before driving on public roads.
Will a bad brake light switch cause my Plymouth Gran Fury to not start or not shift out of park?
Yes, on many automatic-transmission vehicles the brake light switch also feeds the shift interlock solenoid, which must see a brake signal before releasing the shifter from park. Some vehicles also tie the switch into the push-button start circuit. If your Plymouth Gran Fury is stuck in park or won't start, test the switch first.
How do I know if the brake light switch or the brake lights themselves are the problem on my Plymouth Gran Fury?
Press the brake pedal and have someone watch the lights, or use a mirror and a wall. If all lights are out, suspect the switch, fuse, or wiring first. If only one or two lights are out, the bulbs or sockets are the more likely cause. A multimeter at the switch connector confirms whether it is sending voltage.
How long does a brake light switch last on a Plymouth Gran Fury?
Most brake light switches are rated for tens of thousands of actuations and typically last many years of normal driving. Switches on vehicles with stop-and-go commutes wear faster. Corrosion on the connector pins is a common failure mode independent of the switch mechanism itself, especially in high-humidity or road-salt environments.
Is replacing a brake light switch on a Plymouth Gran Fury a DIY job?
For most vehicles, yes. The switch is accessible above the brake pedal arm under the dash, held by a clip or single nut. No special tools are required beyond basic hand tools. The job usually takes 15–30 minutes. The main challenge is working in a confined space under the dash.
