ML55 Electrical Gremlins
2001 ML55
All bulbs and connections have either been swapped or changed to new to verify working condition, however the following Problems have arose:
1) BAS/ESP Light on
2) Driver's side Front and rear Parking lights are out
3) Foglights do not work
So I am convinced that all of these issues are related to one problem. I noticed that the windshield washer tank leaks right onto the ABS pump. I can't image in this is good, a whole gallon just soaked the pump and surrounding connections and this has probably been going on for years.
The fog lights: when pressing the dash fog light button I can hear the relay click in the front engine fuse panel, Fuse 30 is not affected and the green light illuminates in the dash, however the fog lights don't activate.
The front driver's side parking light does not illuminate when the low beams are activated. the signals work fine on both sides, and the passenger side parking light illuminates but not the driver. The same for the rear.
So is there a common theme to all of these issues? Grounding point, fuse that is not located in the front engine fuse box?
I really appreciate the help on this!

Yes it does. Is that light on the same ground/circuit? Basically I need a good wiring diagram. My remote locks do not work either which is a consequence of the aam failure, but would this aam also affect the fog lights even though I have the green light illuminating on the dash and the relay click?
