Radiator Fan Issue

[c6Vette05]

Have been too busy with work and family to work on this, but did try something new today.

Turned on the car, AC off, both fans start at normal speed when car warms up. Turn on AC, right fan stops and left fan goes into highspeed. Turn off AC, right fan turns on, left fan slows down to normal speed.

Is the AC computer controlled by the unit in the console or somewhere else?

Thanks Doubeleive. What kind of maintenance manual is that?

that's a paste from the factory service manual pdf file I purchased off of ebay, the manual runs about $25 or so, it's a little cumbersome because it's not really formatted properly so I just search it with keywords because it is a lot of pages, sometimes takes a lot of clicks to find what exactly you want because layman's terms and technical terms are usually different

I was wondering if I should invest into a copy of the factory service manual or not, seems like it might help. One last quick question, in that screen grab, which one terminal 87?
