Started p5 and shifted from neutral to reverse. No movement, bump or indicator light. Back to neutral, shift back to reverse, nothing. Turned switch off. Turned switch on but did not start engine. All lights turned on including the reverse light. Restart engine, shift to reverse, press gas and get movement. It has been going into reverse all along but there is no amber indicator light or other indication of it being in reverse gear. Checked service manual can't find anything about reverse light. I am sure I'm not looking in the correct place. Any ideas and help would greatly appreciated. Going out tomorrow to pull wiring inspection for signs of rodent damage. Just don't know which wires to to check.
