How do you really know it's not working?
Full Go Pedal = Full Power. No matter what.
Right on both points I believe. Only an owner that uses both modes A LOT, could distinguish with no indicator.
I had my new to me Spark EV at the Chevy dealer yesterday to squeak in some final bumper to bumper warranty work, the rear passenger door wouldn't show as open on the DIC and wouldn't operate the dome light. I determined the pin switch was good, and the wire was connected, I wasn't willing to put forth any more effort with warranty remaining. Dealership technician diagnosis, broken wire. I asked, what do you believe cause this to occur, to which they responded, it broke near the door jam, we don't know. Years ago, when I worked on cars professionally, the only time I saw broken wires was on a couple jeeps and fords in between the door and body.
I was curious if the Sport mode was disabled by a broken wire, leading me to wonder, do we have very weak wires? The Money Pit joke reference aside, I'm curious if there are forces on some harness(es) that are legitimately capable of causing either wire breaks or disconnects at molex connectors. I might go digging one day if I get bored, cause I ain't scured to start disassembling interior panels.
