Selected complaints filed with NHTSA by 2000 Jeep Wrangler owners, lightly cleaned up (personal details are redacted by NHTSA).
I have had this problem 3 times with my vehicle now. The vehicle was having heater problems on highest and second highest speeds. Took the Jeep to the dealership and paid deductable on the service contract in October 2002. Dealer replaced the under dash harness, blower motor and the blower motor resistor. I continued to have problems and took it to my personal mechanic that discovered that the heater control module had failled as well. He replaced the heater control module and Jeep worked fine for 1 year. The heater began to have the same problems again and my personal mechanic replaced the blower motor, blower motor resistor and the heater control unit as well as replacing a burnt wire. The heater again lasted just over a year before actually catching fire under the dash. The entire under dash harness, blower motor, blower motor resistor and heater control unit were again replaced. …
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! …
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 [[VIN]] 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.
Mode selector for the HVAC system has a major issue melting the selector, harness and control module. After researching this incident online and to my surprise there is no recall on this subject. Heater not working, possible heater system catching on fire do hi voltage to the mode selector witch causes entire HVAC failure and possible fire. Jeep has known about this for a while but no one seems to be getting on them about it. Again 2000 Jeep Wrangler heater control failure.
Tl contact owns a 2000 Jeep Wrangler. While driving 30 MPH, the air bag light illuminated on the instrument panel then both the speedometer and RPM gauge dropped to 0. After one minute, the gauges began functioning correctly and the air bag light turned off. The vehicle was taken to a local repair shop but the mechanic could not diagnose the failure. The vehicle had not been repaired. The failure was intermittent. The failure mileage was 67,750 and the current mileage was 67,900. The consumer stated no longer owns the vehicle. Updated 12/30/10
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.
Jeep blower motor speed switch stopped working. Upon further investigation and removal under dash, A/C heater control connector #3 and A/C heater control unit switch were both melted. Replaced the unit and blower motor resistor. Blower motor again stopped working 1 year later. Removed the A/C heater control unit. Both the A/C heater control connector #1 and A/C heater control unit point for that connector were melted.
Consumer purchased a 2000 Jeep Wrangler and was informed that brakes were new and in good condition. Upon putting vehicle in park parking brake did not hold and had to be adjusted. The consumer stated he was involved in an accident when he attempted to apply the brakes, but the vehicle didn't stop. The front pinion seal was replaced and the battery was replaced because it was leaking.
Dt: yesterday the air bag light came on I and the horn stopped working. I was not under recall, dealer going to charge consumer for repairs. Last week the same thing happened with Dodge caravan. They were both Chrysler products ,and the Dodge had a recall. However the Jeep did not.
