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?

Thanks,

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 agree with Mark 100% and have had the same problem. Sometimes a simple on/off/on/off a few times will clean the contacts enough, but sometimes not.

Congrats on your 6.0 and the 7.3 still showing up the 6.0 after sitting for so long.

 

X3 to the above. Maybe your 7.3L is just letting you know it hasn't forgotten you let it sit alone in the shed.

 

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.
