I assume you must have an older G-am since you did not talk about Passlock when you said you installed your remote start. On most GM cars, it is a simple (-) pulse to get the latching relay in the car to activate the defrost. So, just hook up your output wire directly to the defrost if you have the same output. To test the defrost, you will need to use a meter to see what wire does what when you press the button.
