Have 2000 Nissan Frontier. V-6, AT, Air. When driving sometimes the Speedometer, Odometer, Tach, Temp gage, and Fuel gage will stop working for a few miles then come back on. Nothing else is effected, instrument lites, radio, driving lites. Seems to happen when have been driving a few miles and mostly when things like headlites, radio and/or AC is on. Problem always seems to go away if stop and turn engine off for 20-30 minutes. Can it be a relay?
Thank You!

Perform the following to see if you can come up with anything.

SELF-DIAGNOSTIC SYSTEM
ON-BOARD DIAGNOSTICS MODE

1. To activate on-board diagnostics mode, turn ignition on. Change odometer/tripmeter to TRIP A or TRIP B. Turn ignition off.

2. While pressing odometer/tripmeter switch, turn ignition on. Ensure tripmeter indicates 000.0. Press odometer/tripmeter switch more than 3 times within 5 seconds.

3. On-board diagnostics mode is activated. All odometer/tripmeter segments should be illuminated. Replace speedometer (unified meter control unit) if operation is not as specified.

4. Press and hold odometer/tripmeter switch. Gauge indicators will move and become stable after about one minute. Meter/gauge or circuit is faulty if indicators are not as shown. See Fig. 1. Repair as necessary. See FAULT INDICATED IN ON-BOARD DIAGNOSTICS MODE or NO FAULT INDICATED IN ON-BOARD DIAGNOSTICS MODE under TROUBLE SHOOTING.
