Remove the box (ECU), and thoroughly clean it, dry it and retry. Remember to clean its connector pins and plugs. Don't use WD-40, but an electrical cleaning spray like switch cleaner.

Check engine main fuses and all minor fuses.

Repair water leak. Was the leak from the interior heater matrix? If so, then you will need to repair the water leak before replacing any electrical components or ECU.

I unplugged the wire, replaced the fuse and started the car. Then, I turned on the ac button and the fuse blew. Do I need to replace the whole compressor with ac clutch or just the ac clutch? Thanks so much.

Computer box is wet


sure it dont., how can it.?
water conducts electric current. (unless 100% pure)
wet electronics, are a doom thing.... hopeless.
new cars have water proof main boards and 100% water
proof connectors, (not pressure washer safe)
but most dont allow water.
but you never said which computer, my 2008 has 15 computers in the car all talking over a CAN-BUS network.

why not cure the water incursion first.
the dry out the ECU (or what ever computer means)
with and oven set to 125f. (desert temps)

Car wouldn't start .told crankshaft sensor faulty / replaced but still not start & smells as if flood cab


Before you go for anything, try the following: 1) check if there is any spark goes from distributor or coil to leads .
2) check if your car fitted with injection system,if the injectors are spraying correct or are not. If not means that too much fuel in the combustion chamber and kill the spark.
3)remove the spark plugs - after you start for couple of times - if are dry or wet. if are wet probably you have problem with the injector or spark lead,coil or distributor.
4) blocked catalytic converter.
5) ECU ( Electronic Control Unit.) faulty.

Hi, all I have a 2007 velociti 1.6, it's allergic to water sometimes after a wash it refuses to start. I've checked the spark plug leads and the distributor & they fine & dry. What els


I found my problem to be the ht pack.After washing and driving on very wet roads,once the ht pack dried out it worked fine again. Remove the ht pack and close the plug connection and give it a good coating of plasticote70 from crc. this should be available at most electronic suppliers.

Pontiac montana over heated dexcool whent everywhere will not start just clicks


If the car was running when this happened and now it won't start, I would have to take a look at the starter to see if it got wet and make sure it is not shorted out. Also the wiring from the battery to the starter may be wet and shorting as well as something in the fuse box. IF it is clicking then I suspect you have some power to the starter but not enough to turn it over. If you ran the car for a while after it was wet you could have damaged the altenator and it may not be charging the battery and the battery may be drawn down to where you don't have enough amps to start the car. Try jump starting to see if it is related to the battery if not then start looking for electrical shorts in the wiring to the starter.

Computer box problem . The car was submerged in flood, so does the computer box. One Resistor R15 was damaged. Computer box is labeled as 37820-P1E-900 on the first line. Second line is 395-352210...


I would replace the computer box- these can be very pricy! In fact I would recomend replacing the car, you will have nothing but trouble from now on. When a vehicle is submerged, water goes into all kinds of places, and really messes up the whole electrical system. The wires will start to corode from the inside out. The reason for this, is the fact that the insulation on the wire is much like a straw with wire in it. Once the wires get wet in a situation like this, they get wet on the inside also, holding that water, and eating the wire. Every flood car that I have seen, will die a slow and painfull (wallet)death.

check on the passanger side of the car to see if the floor is getting wet as well because it sounds as if your computer is getting wet behind the glove box while at home on a nice day wash the car and check it all over for leaks because the computer or something is getting wet in the car it may be a bad seal around the windshield
