97 flasher / turn signal / trans - related?
I have a 97 F350 4x4 crew (canadian) that was chipped and had an exhaust brake put on it in Canada before I bought it. I've owned for 4 years now and had very little serious trouble with it. I had the trnas fluid changed when I bought it (75k miles) and had a deep sump aluminum pan and cooler installed. I've never been stranded other than a water pump.......and an intermittent power window switch issue(some windows work, some don't from the drivers door....but they all work at the individual door switch), and a drivers door dome lamp swtch that is inop.
Now....at around 150k miles I have an interesting problem. Recently, I noticed that my turnsignals would stop flashing (although they would illuminate the lenses, and the indicators in the dash). Replace the flasher and the problem goes away. A few weeks down the road, it appears again. Today, out of the blue while cruising under a light load, just as the trans shifted into high gear and the converter locked up, the ABS light came on in the dash and the trans shifted out of OD. I didn't realize the trans stayed out of OD as I arrived where I was going. Later, when I left for home I noticed the dash light is still on, I have no OD (pressing the button on the column shifter did nothing), and I have no turnsignals (nothing now at all, in or out of the truck). A check at home of the fuses found nothing, and a check of headlights and tailights found them to be ok as well.
I let it set for an hour or two and just wnt out and fired it up.....yep, abs light is on, and then went out like it's suppossed to. turnsignals ? nadda, nothing, no click, no flash, no nothing. Will a scanner locate this (there is no check engine light, thus no codes? )
perplexed and driving daylight hours only now...yuk!
