We had Cathleen bring us her 1999 Forester because the driver side headlight was out... the bulb connecters were fried and driver side H/L fuse was blown.

We replaced fuse and connectors... everything is now functional with lights, and we moved on to hunt down and kill the short (which we believe caused the problem)

However, there is a loud "angry relay" buzz coming from the Auto Trans pan. It changes pitch with gear change, and when brake pedal is depressed...
The battery seems to be getting constantly drained as well (battery is considered bad already and new one is in route. we have an optima hooked up for the testing)

Any ideas anyone?

that would most likely be a shift solenoid, mileage and when the trans was last flushed can be a factor, it seems you have a parasitic drain, the test to find that is pretty easy to do

buzz disappeared after installing new batt.... never mind
