Aquadoc

Hey guys thanks for letting me in. We need a support support group for sure. I have a question. ..... With my AC or heat on, i accelerate and there is a terrible winding or whining sound until i hit cruising speed. Kinda sounds like an old siren winding up. Doesnt do this with climate control off. 2 years its been doing this. Any ideas? I jave a video of the noise but cant figure out how to post it here. Thank you.
