Abs light is on and abs dont work ,plus reverse lights dont come on for my 1993 grand cherokee

Make sure your bulbs are good. The back-up lights switch is located on your transmission. 2 wires to a little plug-looking thing along one side or the other. If you see no loose or broken wires, you can unscrew the switch and try another. Good luck.

You have to get the abs trouble codes read to find out exactly what part is bad in the abs system.

no, they are 12 volt bulbs and require parallel wiring. If you have a manual transmission, check the reverse light switch on the transmission for continuity with the transmission in reverse. If you have an automatic, the reverse switch is integrated into the transmission range switch at the shift cable attach point. In either case, the wires at the switch are yellow/dark green stripe and brown/light green stripe.

Check and clean the sensor by the tire.

it wont go off unless you replace the bad part/s. Check your wheel sensors for broken wires and check and clean wheel sensor rotors.

Check fuse panel, under dash, as well as under hood. Owners manual should also give you map of fuses. May say"park" lights, "running lights", or something similar.

try to disconect the batery it will reset the computer if the abs light doesnt go off then check your brakes

check the brake switch located on a bracket under your driver side, on top of the brake pedel check for power, if power depress on your pedal see if there's nopower on the other side of the switch then replace the switch. I think it is the switch.

Hello;
Have you checked your fuel pressure and volume? You may not be getting the ful sufficiently to the injectors. Also, change your fuel filter if you haven't already. Is the check engine light on?
Thanks;

Id look at the headlight switch and do some voltage tests to see whats coming out of there. Pay close attention to any wires which look like someone was in there already.People can mess stuff up faster and better than the vehicle can by itself!
