1981-1985 Jeep Cherokee SJ Back Up Light Switch: A Complete Guide
Everything you need to know before replacing the back up light switch on your full-size SJ Cherokee.
- The back up light switch is a common failure item; symptoms are usually no reverse lights.
- Aftermarket brands like Crown and Omix-Ada are the only new options available; Crown is generally preferred by owners.
- Verify your Jeep's transmission type (e.g., T-176, T-177) before ordering to ensure you get the correct switch.
- Replacement is a simple DIY job for most owners, typically taking less than 30 minutes.
Is Your Back Up Light Switch Failing?
On a classic vehicle like the 1981-1985 Jeep Cherokee SJ, electrical components are common failure points. The back up light switch lives on the transmission, exposed to heat, moisture, and vibration. Over 40 years, it's not a matter of if it will fail, but when. The most obvious sign of a bad switch is your reverse lights not working at all, even with good bulbs and fuses. Sometimes, they might flicker or only work when you jiggle the shifter, which points to a worn-out switch.
Safety First
Non-working reverse lights are a safety hazard. They signal your intention to other drivers and light up the area behind you. A non-functional switch can also cause you to fail a state safety inspection.
Choosing the Right Aftermarket Switch
For a vintage Jeep like the SJ Cherokee, original Mopar parts are virtually impossible to find new. Your only realistic option is the aftermarket. The two main players for these older Jeep parts are Crown Automotive and Omix-Ada. It's important to be honest about what these are: budget-friendly reproductions. Quality can be hit-or-miss compared to the original parts your Jeep came with.
- Crown Automotive: Generally, Jeep owners on forums consider Crown to be the better of the two options. They often report better fitment and slightly more consistent quality. Many owners use Crown as their go-to when an OEM part is no longer available.
- Omix-Ada: Omix-Ada is a massive supplier of Jeep parts and also owns brands like Rugged Ridge. While they offer an extensive catalog, some users report issues with quality control and prefer to use Omix parts only when no other choice exists.
Pro Tip: Before ordering, identify your transmission. The 1981-1985 Cherokee SJ could have several manual (like the T-176/T-177) or automatic transmissions. The back up light switch is specific to the transmission model. Check the part number and application list carefully.

Frequently Asked Questions
My reverse lights don't work. Is it always the switch?
Not always. Before buying a new switch, check the simple things first: the bulbs, the fuse for the reverse lights, and the ground wire for the tail lights, which can corrode. If all those are good, the switch is the next logical culprit.
Where is the back up light switch located on my Cherokee?
It is screwed directly into the transmission housing. For manual transmissions, it's typically on the side of the case. For automatic transmissions, it's usually part of the Neutral Safety Switch (NSS) assembly, which is also mounted on the transmission.
Why do my lights still not work with a new switch?
If a new switch doesn't solve the problem, there could be a break in the wiring between the switch and the lights. In rare cases, the internal part of the transmission that is supposed to activate the switch might be worn or broken. This is a more complex repair.
Is there a recall for the back up light switch on my Jeep?
No. There are no active recalls or widespread Technical Service Bulletins (TSBs) for the back up light switch on the 1981-1985 Jeep Cherokee SJ.
