2005 V6 Ford Mustang leaking water onto ecm/bcm causing various electrical problems-indictor lights to come on, fuel gauge to register "E", left front marker light to illuminate with switch turned off, where is water coming in at?

HAPPEN AFTER A RAIN?

OR

COULD IT BE YOUR A/C CATCH PAN (HEATER BOX) THAT THE EVAPORATOR IS IN, IS LEAKING. THIS COULD BE CAUSED BY A STOPPED UP CONDENSATE DRAIN. SEE IF YOU ARE SPILLING WATER ON THE GROUND WITH A/C ON. THIS WILL TAKE PLACE AT THE FIREWALL AREA. IT STILL COULD BE A PARTIAL STOPPAGE.

Just after a very hard rain. Not a lot of water, but any is too much.

Check under the hood near the firewall, look for leaves and other debris, in drainage ports. They might even be stopped up deeper down than you think.

Using a garden hose you may be able to find a stoppage or partial stoppage, that might allow water to back up into a seam (meant to act like a roof shingle, and divert or shed water, not meant to actually waterproof a "Gap")

You may have to run water and use a dowel or similar object to "Poke" thru the drain hole.

So simpler said, make the water drain as it should, around the cowl, and maybe it will not back up and seep in!

Other than that, look for damage or missing or damaged trim that should repel water.

On my '77 CJ5, water is notorious for getting around the windshield gasket and seeping in. The product in this link, is called "Flowable Silicone".

After you 1st apply it, let it sit a few minutes, it will seep into the smallest crack or seam, and it seals really well, I gave my windshield gasket two applications....Years ago, still no leaks!

I hope it is as simple as leaves!

Let me know what you find, as we like hearing, "The rest of the story"
