The last two times I have used my Dart the ETC and Temperature fault light comes on after driving about 15 miles. The temperature gauge also drops to cold, the radiator cooling fans turn on and if I turn off the heater blower, it will not turn back on. After a restart, all is good.
I figure it is probably a break or short in wiring, but I don't even know where the ETC is.
Can anyone help me out?
Thanks
