I changed battery and once reconnected it started and after about six to 10 starts it lockeked up again and the alarm lights are flashing.

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
