Can a faulty knock sensor(P0325) caused the a/c compressor NOT turn on after a timing belt & water pump replacement?

You checked if all plug that go to the compressor are connected?
What year is your GS and is 300, 400 or 430?
On the 300 2002 to 2005 the compressor have 3 wires plugs.
Also, can be a fan relay or fuse that is bad. Check all this possibility please and good luck.

The title of the post has all the car info. Also, nothing was ever disconnected on that side of the engine.
It was working perfectly fine til i replaced the timing belt & water pump. Then, that's when the knock sensor went out. Was able to replaced that w/o any other parts removal.
Will checktcheck the relay to see..

Thanks
