After may trip to dealer for servicing, the low tire indicator would not identify the correct tire. It seems they failed to reset it properly after rotating the tires.
From time to time heater would stay or come on during hot weather and could not be turned off. "Control Head" replaced.
So far so good.
It seems the connector for the cooling fan lost contact and the coolant overheated and was released thru' the safety valve. System was recharged and is now cooling, but still turning on and off. Another vist is likely required.
A/C blower making noise. Remove and replaced A/C Blower assembly.
