trunk wont open at all

BR Got flooded on 8/13/2016. My car was parked in the garage. Got about a foot and a half of water in house. Interior didn't get wet,but my rear back floor got wet. Car lights won't come on. Key won't turn once put in the ignition.

the cooling fan stays on and a/c blows hot air intermittently but fine after overnight parked and then does the same process again. no codes seen when checked by holding the rest and cabin buttons in.

Feels like little to no power is being released from the engine.

no interior cabin heat

When I am driving it is fine but when I turn the car off an hour later the rear of the vehicle raises about 3-4 inches.

Brake lights will not go out when car is started.

I havent drove my car in 2 days and when I went to drive it last night just as i pulled out AIRMATIC TOO LOW warning appeared. I pulled over and saw that my car was sitting in its tires. i turned around and parked it. This morning I go out to check things out when i opened my door I could hear the pump as if it were trying to raise the car, however the car did not move at all. I opened the hood and something shot out litterally when the pump turned off. it seems like a a black rubber circle a little larger than a quarter. I guess what i am wondering is... if the pump is running does that eliminate the possibility that the pump is bad or they relay? i cant drive the car and im single and in college, making 10 an hour in a mortuary... if possible I want to fix it myself.

Been having trouble with the right front side. Replaced the air shock twice and now that side wont raise. The compressor does come on for a lil while then turn off. It seems like there's a leak somewhere in the system but can't find it. But every once in a while that same side will drop down for a lil bit. Then I would have to turn the car off a few times for it to finally air up.

Car stops after 30 minutes and check
Engine light comes on

Both front tires buried themselves in the wheel wells. I changed the pump and the relay. I bench tested the old pump and it worked fine. The car will not air up. I jumped the compressor and set the dash button to lift and aired up the car no problem.it is holding the air with no leaks. I jacked it up again to put the plastics back on and it dumped the air again. Had to jump the compressor again to air it back up. Can anyone please help me??

a mechanic charged me $1600 to fix my AC that was not working my SRS light that was on and now the problem is re occuring. when I start the car many times the AC will not come on,the SRS light is on,the window locks will not work,the windows will not go down and my turn signals will not work. I will have to start the car 5 to 7 or more different times before everything starts working and now the mechanic is telling me it's the control board. What are my options?
