What is wrong with my 2011 Kia Soul +?

What is your question?

All of the following issues began at the same time: Wipers only work intermittently and only on high. Speedometer only works intermittently but is accurate when it does. Inside temperature display shows dashes instead of the temperature. AC blows but no cold air. Horn rarely works. Gear stick is hard to dislodge from park after starting the ignition, also intermittent. The car underwent 3 unusual events in the few days prior to these issues which are as follows: I purchased a new alternator from AutoZone and paid a mechanic to install it. I gave someone a jump and the pouring down rain late at night. I drove through maybe 30 ft of high water but all of the other traffic was driving through it also. I I took it to Kia for diagnosis and they weren't sure what is wrong with it. They said I could try replacing the engine control module for about $2,500 but they didn't know if that would resolve it. I also replaced the BCM and had it programmed by KIA to the VIN and had the very same issues. This has been going on for a year now and I don't know how to get my car properly repaired. Any assistance is appreciated.
