I have a Ford Econoline E-250 that was made into a conversion van. I now have about 82K miles on it and I am wondering if I should go ahead and have the transmission serviced? If so what should I have done and what should I look out for that a mechanic might want to do but really doesn't need to be done? Thanks

Hi there, This issue is in my 2008 Ford F-250, but I think it could relate to most 12v vehicle systems. I’ve read numerous threads on this over the past few days and now I’ve got my passenger seat out of the truck. Before removing the seat, I tested for power and got full power right to the wiring harnesses under the seats that feed the bottom and lumbar heating elements. From that point I get resistance in both bottom pads and good continuity in the lumbar. Fast forward to the upholstery being removed far enough for me to see similar burn marks in both bottom heating elements. (Please see attached pics) In the pics you’ll see that the area where the wire is burnt seems to have the wire still, physically, in tact, but burnt nonetheless. My question is, would you recommend splicing some new wire into the burnt area, cut the burnt area out and solder the fresh ends together within the pad, or... ? I’ve done my fair share of wiring repairs but just haven’t come across a burnt area within an in-tact wire before. I’ve got upholstery felt, heat shrink tube and all that fun stuff for reassembly. I forgot to mention that the burnt wire area is right where the heating element transitions from butt warmer to thigh warmer, and I could see this being a common wear area based on people getting in-and-out of the truck on a regular basis. thanks for reading my post!!
