Loud hum from engine bay
Hi, I'm hoping someone can help me figure out what's wrong with my car.
I recently changed my power steering pump, with required removal of a lot of things in the engine bay. After I installed everything, I'm now getting a loud hum, really more like a constant tone from the engine bay. Is hard to pin point the exact location (I need to find a hose somewhere). The sound appears when accessory power is applied, and removing fuse B8 (think that's right) stops the sound. It's a tone with a frequency of 1800 Hz with a strong second harmonic at 3600 Hz.
The fuse description says it's the alarm, but I though that was under the hood.
Attached is the spectrogram (I couldn't upload a video), and a picture of the fuse that stops the sound when removed.
Thanks in advance!
Bryan
