Hello all. I've got a 2010 TC and have an electrical gremlin that would make Lord Lucas proud. The truck will be running and I'll do something like step on the brakes or turn on the turn signal and the dash lights will flicker/click several times and sometimes everything returns to normal, sometime all the electric completely shuts off. If I'm idling in park I'm stuck in Park and can't shift until it decides to turn back on. I'm thinking it is a grounding issue, but was hoping to get some direction about where to look (my local dealer said there are something like 157 grounding points). I can disconnect the ground from the battery and then after reconnecting everything is good for a few on/off cycles. Also, the hotter the outside temps the worse it is.
Any advice is appreciated. Thanks!
