Controlling a turret's idle animation (Animator) along with look towards target (script) together

I've got a tank with a turret that rotates to where ever a ray cast collides with the terrain. Works fine but i wanted to create a 'scanning' / idle animation for it where the turret looks left and right when it doesn't have an enemy. Problem is when i put the animator on it stops the turret rotation script from working.

Ive setup a few bools on this, one is an enemy near bool and also a hasMoveTarget bool

i was wondering if there was a way i could only play this idle animation when a move target or no hostile is near ? Wanting help running both a script based 'animation' and an animator driven idle animation.

Thank you

 

I have similar, but I just procedurally use a sine or sawtooth formula and a clamp, to animate the idle search time.

You could enable/disable your animator component when you acquire/lose your target.

 

so i tried this, but the problem is the moment i put the animator on the turret SNAPS to the start point of the animation (looking about -65 left) so i think ill do this with code, wish there was a way to interpolate from its current state to the animator start pose...is there ?
