A few weeks ago I was offroading, and at the end of our day we decided to go on a trail that was flooded with about 6-8 inches of water. I had been on this trail many times before and was very familiar with it as it is on our family farm. I was about 3/4 of the way across when the trail collapsed (seemingly because it had been submerged for so long and the ground was too soft for the Range). This is the result:





We eventually got it pulled out and dried out. I took apart the BeCM and cleaned it with compressed air, electronics cleaner and MAF cleaner. After drying everything else out, we hooked up the battery and it started right up. The passenger side amps were blown, they have been replaced. I have ordered a new front passenger door lock, because it would not open and we had to break the door latch, as directed here http://www.rangerovers.net/repairdetails/doors/doorlocks.html.

I drove the range around and it kept saying that lights were going out, the rear in particular. Event though some of the lights were not submerged it is still saying they are bad. No lights on the passenger side tail light work, the reverse lights don't work, and the license plat::e lights don't work. Also, the only brake light that works is on the driver side. These were fine when we first started the Range up, but went out as it was running. Strange, but not major.

The major issue I am having is when the Range has been turned off. It ran perfectly smooth and did not even hesitate. However, when it was turned off it was doing this:



I don't know why everything was going crazy, or what that noise is. It also sounded like it was making the compressor come on. Also, after about 30 minutes of driving the Range around, this issue drained the battery to the point where it would not start again - dead battery.

Any ideas? Thanks so much for the help!!!

Ouch.... A perfect example of why I don't wheel anymore in FL. Especially in the P.

Relay buzz...hmmm. Does it do it when you replace that relay with another one? Does the buzzing relay buzz when you put it on a different slot?

I'm thinking your becm still has some water in it. Maybe try removing it and letting it air dry for a couple more days.

OMG that SUCKS! Mine made buzzing noises after I pressure washed the engine bay :doh: . Thankfully disconnecting the battery and letting it sit and dry out for a couple of days fixed the problem, it wasn't that bad though. But man, you are probably looking at a new BECM and everything :oops: If I were you, let it sit wit the battery disconnected for least 3 days in a warm spot to dry, oh and pray. Might also want to take the becm out and let it sit inside to dry.

Did you use a dehumidifier on the inside? If not you will have alot of moisture that can condense in the BeCM causing problems after you have already dried it out. Also run the electrical tests in the stickie above. If you are not charging while driving your alternator may be shot. Low voltage will cause all sorts of ghost errors.

When I replace the relay with another one it does still buzz, and when I use the relay in question in another spot, it seems to work correctly. It has been since the beginning of December since I sunk it, so the battery is dry. I will pull the BeCM again and see what I can do. No dehumidifier, just air dry. I do suspect that the battery is shot, and I will test the alternator too.

Pull up your carpet by the doors to see if the insulation is still wet. You might have to take out your seats and pull out all the carpet and let it dry in your garage to get it perfectly dry. It will also be a good time to rent a steam cleaner and take care of all that scumwater that impregnated your carpet.

If I were you I would follow mags advice, get the seats and carpet out mold will grow, If you want I can send you front and back carpet for a nominal fee. (saddle)
