Without any more information or details to go on, if multiple systems are having problems at the same time, suspect a charging problem. The generator is not recharging the battery while driving. You can verify that by measuring the battery voltage. With the engine off it should be 12.6 volts if it's fully charged. If it's good but run down, it will be closer to 12.0 volts. If the battery has a defective cell, it will read less than 11 volts.

With the engine running, it must read between 13.75 and 14.75 volts. If it's low, suspect the generator or voltage regulator.
