Howdy, I hope I posted this in the right place.
I am new to the Jeep thing and have some issues with my 2001 Cherokee (6cyl 4.0) basically the Instrument cluster isn't working with NO BUS shown after the car is on. sometimes the mileage will display but the gages never work, Radio screen doesn't work 99% of the time, and when the car is off pressure builds in the coolant system, so I bleed coolant. I cleaned the connectors and checked all the grounds. I've flushed the coolant system three times. I can't figure it out. the battery also discharges power, i replaced the battery and that is also still happening. I feel like its a bad ground but all the grounds i can find are good. any help will be greatly appreciated. It's worth noting that its rough to start but runs and drives fine.
