Well, first off, like I said, some bragging. As most know I bought a 6.0 last year, and that has been my main vehicle over the last year. Its great, I really enjoy that truck. As such my 7.3 has been enjoying quite a bit of time off, for instance, it sat in the shed since about mid August. Anyhow, yesterday I decided I better bring it home to be my winter driver/ backup vehicle, as the 6.0 is used as a DD to haul the kids around. I walked out to the truck, stuck the key in, gave the glow plugs 30 seconds and it fired up. I was quite impressed with the 17 year old, 268k mile truck running on the original starter, injectors, and 5 year old batteries. Just wanted to share that bit, thought people might like it.
Now to the question. While driving home last night, I discovered that my high beams do not come on if I throw the selector switch forward like normal. However, if I pull the selector switch back towards me, they will come on "momentarily" as designed. Does this point towards that multifunction switch being bad?
I would think so but can't say for sure. I have found that electrical connections will gather some oxidation when left to sit for a while and I have had some luck working them and getting them to work...so give it a workout and see if it helps.
I tried the old "on-off" thing where I just sit and brain dead like flip the switch back and forth. No luck though. I think I will pull the column covers off and inspect the switch when I get a chance.
I think you are right about the truck though, last year it surprised me as well. It had been sitting outside most of the winter and was stuck in about 2 inches of ice. I needed to use it cause one of the calipers had seized and broke a piston on my 6.0. anyhow, same deal, let the glow plugs go and she fired up, at 20 degrees or so. Such a beast.
