I have a 03 ram,up to now i have had little to no trouble,the truck has 144,000 miles,whenever i start my car the headlights come on automatically,wipers only work if i turn them on when the car is off then start,and to turn them off,i have to turn the truck off,then turn the wiper switch off,then restart,i have no high beams,ac is now not working,my brakes lights are not working,just about every engine light is on,all gauges do not work and were my odometer is located it says NO BUS. Does anyone have any idea whats wrong??I just purchased another brain/power control module and it did not work,ive never seen anything like this in a truck or car.Please id really appreciate any help,this is my only vehicle and i have limited funds.Thanks.

 

This could be an issue with wiring harness behind the instrument cluster or the gauge cluster itself not being able to communicate with the computer. The connections can become dirty or become unseated. You can clean the connections with electronic contact cleaner. If that doesn't work it could be the gauge cluster itself which can go bad. If in that case it would need to be replaced...Hope this gives you an idea where to look...Mike
