No Dash Lights or Tail lights

[TheDirtyJeep401]

86 Comanche 2.5.  When I replaced the clutch master cylinder a couple of weeks ago, the rear tail lights no longer work. Brake lights and turn signals still work, but no rear lights when the headlights are on. Also the gauge lights don't want to work. The lights for the Coolant and oil pressure and everything still work. Just not the backlighting. Anyone have any idea what it could be?

Check your fuse block for damage from clutch fluid (assume the cylinder was changed due to leakage?) Also, could have disturbed some fuses or wiring under the dash. Recheck the fuses and connectors, refresh your grounds.

The cups in the clutch master cylinder failed. Wasn't leaking too bad. Ill check the box again. Do you have any wiring diagrams for the lights/Under dash wiring?

Check and see if someone connected the plugs for the trailer lights by your rear bumper, I had the same exact thing happen to me. They are not supposed to be connected to each other.

So I replaced the headlight switch. Still nothing. Checked connectors and refreshed my grounds and I still have nothing.

Those 2 things share the same fuse........

X2 :agree:  it's easy to overlook the obvious, ask me how I know.

None of us are exempt from that error.....

I got it fixed. Turned out to be a loose wire and 2 fuses that seemed fine until tested. Now to just figure out why the power outlet doesn't want to work......
