I pulled my bumper off and found this thing inside...it disappears on top of gas tank and I can't find its other end... It makes a hissing sound and I'm just curious as to wut it does...




I'm also stumped with my left rear reverse and brake lights, turn signal works and both non working lights have new bulbs and wires have continuity and no shorts...everything on right rear side works...wondering if anyone has a suggestion for that cause there's no shorts and new bulbs and still can't get em to work

Thx

 

I'll take, what is the Schrader valve filler for the rear air shocks for $1000 Alex. You might want to snug up the fittings and put more than 20-30 pounds in there to protect the shocks. Mine take less than 80...50 is normal. Yours may be different! You may want to check, but put at least 20 in there. .

 

Ahh I could see it being that...they wouldn't be doing anything right now though I'm on my third set of shocks since owning this jeep and the current ones are blown to lol

 

Lights: Pull the rear quarter panel (behind spare) and check the MOLEX connector. I was having similar problems and discovered the PO had someone install a trailer lighting "kit". This kit apparently came with a razor blade, some 22 gauge speaker wire and a small supply of duct tape. At the very least, having the panel off makes it easier to trace.
