My jeeps been acting funny lately, the dash lights for the odometer and clock blink when the turn signals or brake lights are on, if I shut the all the lights off and hit the break pedal the dash will light up, also the airbag light is on, any help would be appreciated thanks

Sounds like you may have a ground issue somewhere. Many strange things happen in an XJ when the grounds become corroded or loose.

Has there been any mods to the Jeep that would have involved wiring under the dash? In the engine bay?

Was the HVAC Unit changed for a heater core change, etc.?

I haven't done much under the hood recently, it all started when I had a flat tire, didnt have a jack so these kids helped us lift the back of the jeep are there any grounds back there that could be the culprit? We picked it up by the passenger rear corner under the tail light and bumper

There's two ground points, splices, and connectors behind the spare tire mount. But there's also some wiring that goes along the passenger side opposite this spot that you may want to check out as well.

These circuits may have nothing to do with all your varied faults but there's no sense in overlooking them.

See pic for locations and lists of ground circuits.

I finally got around to fixing it. Turns out my tire took a bite out of my bodywork, I didn't find any grounds but the connector for the tail light was filthy, I cleaned the connector and filled it with dielectric grease now the lights work like they should, the airbag light is still on tho, thanks for the help
