Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

You can't do without the C wire. There are options but I need to know what you have for heating equipment and what termnals are connected on your existing thermostat

I have a heat cool system with an old white Rodgers thermostat with a four wire system colors black white green red hooked to rh jumped to ra

model of thermostat is 1e56w-309

Ok, The easiest way to solve your problem is to move the lead currently on G to C both at the thermostat and at the furnace terminal strip. Then install a jumper between Y & G at the furnace terminal strip. The blower will still function in either heat or cool modes but you will lose the option to turn the fan on manually at the thermostat
