I have a 2000 Jeep Wrangler Sport with about 120K miles on it. Every winter my heat goes out, and I spend at least 2 weeks of the winter making repeat trips to the auto repair shop--first they replace the resistors, then the relay switch, the blower motor, etc. I have also had the no bu5 come on my gauge panel, and I register a speed and RPM of 0. A couple of weeks ago, the battery gauge started going wild, and then afterward I cannot start my car. I have noticed that if any of the gauges are off I will experience the same thing--sometimes it is the oil gauge. I cannot count on the gas gauge, but that does not seem problematic. I have lost 2 days of work with my car in the shop this week and they will have it again Thursday. Still, the problem persists. Has anyone else dealt with this? Thanks!
