What 1999 Jeep Wrangler Yj owners say
Most recent owner complaints, unedited.
The exhaust manifold headers have cracked in two separate locations. The first crack is located at a bend in the header and the second crack is near the weld at the flange where it connects to the exhaust pipe. This location has cracked completely around the pipe, mostly at the weld but upwards 1/2" into the manifold itself.
The airconditioner switch has melted 2 times since I have owner this jeep. Dealer says nothing is wrong. No add on equipment of any kind is present other than a cell phone charger in the cigar lighter receptacle. There had been no fire yet...but the wires are getting hard and brittle. The first switch just showed some melting of the plastic on the switch housing. The second switch had the metal lug that the high-speed fan wire connets to completely loose from the switch and hanging in the wire connector. I have been to 2 dealers and both said nothing was wrong...I must have just gotten a "bad" switch. But they still charge me about 80 dollars for a new switch panel each time.
When opening gas cap, flames came out of tank, unable to determine cause.
