Try the touch test
Get some paper towels and press them against the low spots in the carpet. The paper towels will draw the moisture out and reveal if the carpet is wet under the surface. Some carpets can be several inches thick to insulate from heat and sound. If the paper towel becomes wet it could mean water has gotten into the car.
Investigate the interior
Look under the seats and dash for corrosion and rust and look for exposed metal that is untreated. There are metal springs under the front seats that are usually not painted. If they are rusted that is a sign the interior has been wet. Look for mud and debris in places it does not belong.
Inspect the instrument panel
Turn on the key and perform a bulb test. Make sure every bulb lights up. If a system has an issue, removing the warning bulb can hide it. Many times vehicles that have flooded have malfunctions in their anti-brake and air bag systems. Ensuring the light comes on and then goes out after the bulb test is an indicator that the system is on and has no active faults.
Take it to a professional
Let a service and repair technician inspect your vehicle. They can raise the car and look underneath to see if there is any mud, sticks or rocks in the suspension. A professional can check the oil in the differentials to make sure they contain no water in them. Spend a few dollars to have it looked over to give you peace of mind.
