2000 Jeep Wrangler electrical problems

While driving down the road, speed doesn't matter bc it has happened at multiple speeds, the speedometer and tachometer will drop to nothing, while the other gauges like gas, oil pressure, temperature and such do not have any issues and remain where they should be! A few seconds after the speedometer and tachometer drop, the engine light comes on and the odometer will read 'no bus', a few seconds to a minute later the gauges will resume and the engine light and 'no bus' disappear! Another example of this is the speedometer and tachometer will drop and other gauges not be affected like previous scenario only with this one the airbag light will illuminate, lasts for a brief period and then goes back to normal! It happens sporadically, but have noticed it happens more on bumpy roads! None of this has happened while the vehicle is stationary at idle! All while driving down the road, various speeds, various types of roadways!

Over heating of A/C - heater control switch while in use caused the switch connector, switch and part of the HVAC control panel to melt. On the verge of fire the fan stopped functioning. Retrieved the same unit off a doner vehicle [1j4fa59s3yp733181] and found the control to be melted/burnt in the same fashion. When I looked for a replacement, the parts suppliers offered a ready-made replacement wire harness [potential clue of common failure]. The mopar replacement part is listed as discontinued. I have taken photos of the issues described, but will have to get them developed and digitized [my digital camera won't take close-up pics].

2000 jeep wrangler. The wiring to the A/C control switch shorts out and causes a minor fire. The switch has been replaced and it happened again. There was evidence of a previous fix in spliced wiring. The wiring harness is no longer available. Research on jeep related web sites has proven to me that this is not an isolated incidence and occurs in many of the surrounding model years. There is a design flaw in the three posts that connect to the selector switch, they are to close to each other.

Hvac wiring harness and switch melted due to faulty blower motor compounded by inadequate size wire. Chrysler does not even sell a repair kit even though there are new cases constantly on the wrangler tj on intranet forums. Some are even vehicle catching fire.

Instrument cluster will intermittently go out, leaving no speedometer, odometer, or RPM gage. This can go out for several miles, or just blink on and off. It has been doing this for a couple of years, and have already attempted to have it fixed once by a dealership and several times with my son working on it. So far nothing has corrected the problem. Dealership knew what the problem was when first brought to them about 2 1/2 years ago but could not fix the problem. Being on the community emergency response teams, I need a reliable vehicle.
