1992 XJ Laredo, brake and hazards not working.

My daughter bought a 1992 Cherokee Laredo yesterday for $900. I went through it to make sure everything checked out but after she paid them and I followed her home I noticed the brake lights were not working.

I figured it was the fuse but I'm not sure if I found the correct fuse. I found a post in a Cherokee forum that states "the 15 amp mimi fuse in the engine compartment marked HAZ lamps" is the one for the brake lights. I checked that fuse and it was fine. I went through all the fuses at both the engine compartment and under the dash and they are all good.

I figured it was just a brake switch and thought I'd check all the lights. I noticed that the hazards were not working either. I don't think the brake switch would affect the hazards but there is several wires going to the brake switch.

Any suggestions on what I should be checking for? My daughter spent all her money getting this Jeep and doesn't have a lot for repairs right now, so I'd like to make sure the part is bad before I go around buying new parts.

TIA

Have you checked the bulbs? When I bought my old car, 3 out of the 4 bulbs in the tail light housings were burned out. It's worth looking at.

I checked the bulbs, they are all still good. I even had a new one from my Grand Cherokee (needed one, two came in the pack) so I put that one in and still not getting any brake lights.

If the hazards are turned on, doesn't that flash the turn signal bulbs? I'm wondering if the hazards and brake lights issues are not related to each other.

Also the brake switch has 6 wires going into it, which I thought was odd. In other vehicles they only had two wires going to the brake switch.

I think I figured it out. There is power going to the fuse under the hood but when I checked the voltage going to the switch I'm getting under 1 volt to it.

I used a jumper wire to provide 12 volts to the switch both the brake lights and emergency flashers worked. So obviously there's a break from the fuse to the switch. More than likely under the hood somewhere.

It's been a while since I posted on this thread, but I wanted to post an update. After doing a LOT of troubleshooting I found a short in the rear pillar where the wires go from the driver's side to the passenger side. I couldn't reach where the short was so I just cut the old wire and ran a new wire through the pillar.
