Fixing the Back Up Light Switch on Your 1986-1994 Dodge Colt
If your reverse lights have stopped working, the switch on your transmission is the likely cause.
- The most common symptom of failure is reverse lights not working; always check bulbs and fuses first.
- The switch is located on the transmission and is a simple DIY replacement for most owners.
- There are no recalls or TSBs for this part; failure is due to normal age and wear.
- Standard Ignition and Beck Arnley are reputable aftermarket brands for this part.
Is Your Back Up Light Switch Failing?
A bad back up light switch usually fails in a few predictable ways. Before you buy a new part, make sure you've checked the easiest things first: the bulbs and the fuse. If both reverse light bulbs are burnt out, you'll have the same symptom as a bad switch. If the bulbs and fuse are good, the switch is the next logical part to check.
Common Symptoms
- Reverse Lights Don't Turn On: This is the most common symptom. You shift into reverse, and nothing happens.
- Lights Work Sometimes: The lights might flicker or only work if you jiggle the shifter. This points to a worn-out switch or a loose connection.
- Reverse Lights Stay On: Less common, but the switch can fail in the 'on' position, leaving your reverse lights on constantly and draining your battery.
Choosing the Right Aftermarket Switch
For a vehicle like the 1986-1994 Dodge Colt, the original OEM (Original Equipment Manufacturer) switch is likely discontinued. Aftermarket parts are your only realistic option. The quality of aftermarket electrical parts can vary, but the brands available for your Colt are well-established.
Aftermarket Brand Tiers
| Brand | General Quality & Reputation |
|---|---|
| Standard Ignition (SMP) | Often considered a top-tier aftermarket brand. They manufacture many of their own parts with a strong focus on quality control and testing to meet or exceed original specifications. A reliable choice. |
| Beck Arnley | Focuses on sourcing parts that match the original's form, fit, and function for foreign nameplate vehicles. They have a reputation for providing parts that are direct replacements and work correctly out of the box. |
| Facet | An Italian manufacturer that produces a wide range of automotive electronics. Generally seen as a budget-friendly option that is often better than no-name parts, though some users prefer to use premium brands for electronics. |
Pro Tip: Since this switch is a simple mechanical part and not a complex sensor, any of these brands should provide a reliable repair. The price difference is small, so choosing Standard or Beck Arnley offers extra peace of mind.
Known Issues, Recalls, or TSBs
There are no specific recalls or Technical Service Bulletins (TSBs) from Dodge or the NHTSA related to the back up light switch for the 1986-1994 Dodge Colt. Any failure is due to the age and normal wear of the component.
Frequently Asked Questions (FAQ)
Where is the back up light switch located on my Colt?
The back up light switch is screwed into the transmission. On these front-wheel-drive cars, it is usually located on the top or side of the transaxle, visible from the engine bay. You may need to remove the air filter box or battery to get clear access to it.
Is this a difficult part to replace myself?
No, this is a good job for a beginner. Once you can access the switch, you simply unplug the electrical connector and use a wrench to unscrew the old switch. Screw the new one in, plug it back in, and test it. The most difficult part is usually just reaching it.
What tools do I need to replace the switch?
You will need basic hand tools. This typically includes a socket set or wrenches to remove the battery or airbox for access, and an open-end wrench (often a larger size like 24mm or 27mm) to remove the switch itself.
My reverse lights still don't work after replacing the switch. Now what?
If a new switch, good bulbs, and a good fuse don't solve the problem, you likely have a wiring issue. Check the electrical connector for corrosion. You can also use a multimeter to test for power at the switch connector when the key is on and the car is in reverse. If there's no power, you'll need to trace the wiring back to find the break.
Technical Specifications
Typically a 2-pin, screw-in switch located on the manual transaxle.
