I, like an idiot, left the run roof open on our ‘19 XC90 last night and it pored rain in it. I shop vacuumed all the water out and ran a box fan. Floors seem like they’ll dry fine but when I crank it up, every dash light comes on. Check engine, transmission, anti skid, everything everything....what do I do? I could really use some help so the wife doesn’t kill me.

thanks for the help

 

Nothing to add here? No advice at all?? Come on guys

 

check fuses etc? remove interior trim under the dash to let anything that may have gotten wet dry out. I'd also look at removing the shifter's trim as that's tied into the start circuits etc. Did you disconnect the battery while the car was drying out? quite possible you are seeing low voltage which can mess with all the sensors etc. Dry the car's interior as best you can then check battery voltage. if you have a charger, you can try disconnecting from the car and get it back to a full charge before hooking back up.

 

Strip the interior. Pull the seats. Pull all of the carpeting and anything under it that can be pulled. Suck any water out. Disconnect any electrical connectors (one at a time). Use compressed air and blow them dry. If there are any modules under the carpet and they have been sitting in water they may be dead.
