Someone please help answer this I have a honeywell thermostat.the wire colors are r,rc,b,w,g,y. is it o.k.to hook blue to w,and white to y, to see if that will make the a/c come on?

R is generally jumped to Rc UNLESS 2 low voltage power sources.

Rc to Y; turns on outside unit
Rc to G; turns on inside fan

For AC, the thermostat controls the fan

Make connections with power off and wait about 5 min after power up. You can blow the main AC fuse if the compressor turns on after just turning off.
