Back up lights doesn't work

Sounds like the back up light switch may have gotten unplugged. It is on the left side near the rear of the transmission.

If pushing on the area makes them work again then there is obviously a loose connection there. You will need to inspect the wiring and connectors at the rear taillamp assemblies.

Should be able to see the wiring in trunk, maybe under carpeting, without removing the lamp assembly.

Check the "neutral start switch" for proper operation. I believe this year, it also operates the reverse lights. Also have your linkage cable(s) adjusted properly

Turn on the key cycle the prindle to see if they blink on. The reverse lights run off the neutral switch. Its wereyoull see it under the shift cable their are 2 13mm screws holding it the shift cable hooks to the transaxle. Key on and shift to rev. Then lossen the bolts and turn it l and r when you see the reverse lights come on tighten the switch. If no youll have to replace the neutral switch.

Make sure the car starts in park and neutral and the rev. Lights work when done.

If the turnsignals work the switch is bad or open harness. My answer is for a automatic where pro is for manual

With my Jeeps, the darn connectors will come off of the Back-up light switch. From bouncing around. Yours could have done the same!

To verify if you got a bad B/ U light switch on your manual tranny

Remove the connector to the back-up switch, then jump across the connectors 2 contacts (paper clip, etc)

Then turning your key to the "ON" position, will FOOL your system into thinking the switch was turned on by the Gear Shift

If your Back-Up lights do come on, You most likely have a Bad Switch (or something in the tranny ain't activating the switch.

I would sling you a Picture or Diagram of exactly where the switch is located, but I am unable to locate one on the On-line Repair manual, I have access to.

Let us know the deal, or even if you get bogged down, and something else may be wrong

BE SAFE, CARS ARE HEAVY, DON'T BECOME A STATISTIC!

If it is a automatic refer to my first answer. If its a stick there is a switch on the transmission like protech said. Any parts store will sell it to you. They show where it goes thru diagrams.

Have you checked the main fuses under the hood? Are you certain that the ground from the new battery is tight, clean, making good contact, and is properly installed. Some of these vehicles had a small ground off the main one which ran to the inner fender to provide a better body ground.

Also, I need to know if by back lights, you are referring to the rear of the vehicle. For example, brakes, turn signals, parking lights.
