when I turn on the a/c in my sons 2004 monte carlo nothing happens.
There is no sound, from when I go from off to on. nothing happens. it is like I
never touched the switch. I have the car running with the hood open and
nothing happens under the hood, no click when turned on, no clutch
engagement. It is as if I never turned it on. It seems like there is no electrical
current. fuse is ok, possibly a relay?
