What I don't get is why higreenX5 starts pulling fuses when things are not working. To see if they are blown?
>higreenX5: A quick way to find blown fuses without yanking them out is to get a simple lit ciircuit tester probe like this, (Craftsman sells something similar for much less):
EECT300HR, Tester, Circuit, for 6 and 12V Systems, Red
Connect the aligator clip to a good ground. While the ignition is on, you can touch the end of the probe to each fuse. The fuses have a tiny "window" at each end with exposed metal. Touch this, and make sure the probe lights at both ends. If it does, the fuse is good. In about 30 seconds you can check the whole fusebox. You might want to check both fuse boxes; the one in the rear, and the one over the glove box. NEVER switch in fuses of the wrong amperage. Go to an auto store and buy an assortment so you can put in the correct replacement for any blown fuse.
But while my earlier post poked a little fun, my story about the Porsche was for a reason...to show how potentially grave the damage could be by dumping water into the electronics. Even componenets that can be dried out and made to work can have their lifespan shortened dramatically due to corrosion of internal components.
Aside from checking the fuses, you are getting into an area where only the most skilled automotive diagnostic technician will have success. If you can narrow down exactly what got wet, that might give a leg up, but with cars with all sorts of interconnected electronics, it is not uncommon for a bad module to cause another downstream to fail. In reality, any electronic module that got really wet should be replaced...plus any that failed secondarily.
Finally, have you considered an auto insurance claim for this car? This was accidental damage, and repair costs will likely exceed your deductible if you have "Comprehensive" coverage. In my story about the Porsche, the only way Porsche was willing to honor the warranty down the road was if 100% of the components that got wet were replaced. This car had all sorts of electronic wackyness going on after it's bath, but this remedy went WAY beyond just fixing the haywire components. BUT that's the only way to make the car 100% again. All that was left was the bad Carfax, which BTW, Allstate paid about $8k for reduced resale value of the car as part of the settlement.
