well, this 97 here is in deed cursed.
Key off draw is randomly 4.5A, sometimes less, still always well above the 50 ma level.
Weird things
HVAC blower occasionally doesn't shut off with the key. Pulling the IOD or Blower fuse will turn it off.
Pulling the IOD fuse kills the current draw (and the dimly lit dome lights)
Sometimes there's a high pitched whine from the engine compartment, corresponds with key off draw. Pulling fuses kills whine.
Turning on the dome lights will kill the excessive draw and show 800ma, in line with two light bulbs.
Before I pulled the rear defrost relay the indicator light would glow with the dome lights. Pulling the rear defrost fuse in the PDC killed the current draw. (for a day)
Sometimes the gauge cluster works with no IOD fuse, sometimes not. Always with. When the cluster works and no IOD fuse it appears that the alternator isn't charging battery.
radio wiring was a mess, but I fixed it.
washer bottle was missing and wiring hanging, it's been taped up, no change. Sometimes the low washer light comes on even though it's not hooked up to anything.
Grounds on the side and back of the engine have been cleaned and checked. I have not gotten to the one in the rear by the hatch yet.
I can't find any single point where these circuits all interact or are connected.
starting to suspect the ignition switch having some sort of short, but how does that ground through the dome lamps?
looking for ideas.
