Can someone check this circuit,?

A little background on this one: 2009 Honda Ridgeline. Clifford 4706x remote start. I'm attempting to hook the driver's side seat heater and mirror heaters to the defrost output (blue/white) of the remote start. Both are latched 12v circuits. I've set the remote start output to latched on the defrost wire. The seat heater is a three position switch: High, low, off. In the seat itself, the high and low circuits meet. The low side just has some resistance. I want to keep there from being double 12v to the seat. That would be a scenario where the switch was set to "high", the remote starter is used, it's below 55 degrees and the circuit energizes the "low" seat heater side. Can someone review my circuit and let me know if I've imagined this correctly. Also, I'm using diodes to isolate the mirror circuit from the seat heater circuit. Thanks!
