Weird symptoms..air conditioner stops blowing out dash vents and stops responding, Nav/radio turns off, cruise no work, engine surges, tranny hard shifting first to second gear. I stop turn off truck and restart it and everything works again.
Any ideas????

WOW! Well tranny / engine codes are related to "extensive electrical problems" with codes in all modules except ABS. TCM TCCM ECM IPC SIR about 15 items and a lot are lost comm
