My '86 J20 did not have any running lights.
I determined that the Headlight switch must be the issue, so I decided to replace it.
It had been highly recommended to me to gently pry off the trim without breaking any of the mounting tabs; remove the instrument cluster;
and then this switch replacement is a 5 minute job.
The idea of removing this trim scared me to death.
Can I pry off the 36ish year old, sun baked trim without breaking it? I seriously doubt it.
Will I listen to seasoned and experienced Jeep owners and not attempt this repair with the instrument cluster in place?
Come on, what do you think?
I was able to reach up under the dash and pull the plug off of the existing switch.
Using my fingers, I was able to gently pry up and release the top tab on the switch and then the lower tab...and it fell into my hand.
So, what do I do next? Install the new switch of course.
This was unwise, as I struggled to get the connector on the new switch.
I thought for a moment I was going have to risk breaking the tabs to get the new switch out, plug in the wiring harness and then reinstall the assembled switch.
While is was not easy, I was able to get the connector on the new switch with it installed.
Now, I have running lights! Success!!
