A week ago I noticed when I got in my truck and started it the OD light showed off, seemed strange but pushed the button and it the light went out. All was fine for a few days untill Wednesday night. The wife and I were headed out and all of a sudden the light started coming on I would push the button and it would turn off. This continued for the whole evening. Next day I pulled the column apart and checked the wires to the switch found a small worn spot, I repaired that checked the rest and put it back together. Still did the same thing! The next day I took it to a trans shop thinking maybe it was flashing ireatic codes, my scanner won't read the trans codes. The tech came out scanned the truck ran some self test and it passed. So he took a test drive with me the light started turning on and he said on the scanner it showed it was activating and deactivating. I figured it had to be a short maybe the swhtch itself? I went and got a new assembly installed it and still the same issue. I the crawled under the truck and checked connections at Mlps, trans connection and pulled cleaned and checked wires to VSS. I'm stumped. All the info. I can find always points to a flashing light which I don't have I have a light turning off and on on its own and no trans or engine codes.
