more 300TE Weirdness - noise from rear when OFF

[reddirtranch]

When troubleshooting my blower problems, I had the key out of the ignition and heard a noise like the fuel pump in the tank coming on for a few seconds and then off. It sounds like its near the rear passenger wheel.

Would this be normal? I've had this car for 2 years and never heard it before. ? possibly related to the lack of control voltage on my blower ? Advice from an expert is appreciated.

Thanks
