The drain pan is under the evaporator. The noise you can hear is air in your coolant system trying to get through the heater matrix. Water doesn't slosh when you are stationary and just started the car. https://www.fixya.com/cars/r29872074-vehicle_cooling_system_no_heat ..

Check for battery power on the orange wire pin D and ground (black wire) pin C- Brown wire pin B should be ignition hot on connector C1 on the Driver Climate Control Seat Module located under the driver seat. If you have power and ground, you may need to use a scan tool to see if there are any codes stored in the module. If the scan tool is unable to communicate with this module, it could either be a bad module or a network problem. If you are missing either battery, ignition hot, or ground- then repair as needed

I think your problem is most likely going to be battery corrosion on the positive battery cable. Take the positive cable off and look at the side that connects to the battery- if that has a bunch of white stuff on it, mix up some baking soda and water use a tooth brush to clean the terminal off and rinse with water. Then spray with electronic connection cleaner and apply some dielectric grease to the connection before you put it back together. I have had to cut the rubber part of those cables in order to really get in there and clean things up- sometimes there will be a bunch of corrosion around the little 8mm lug that you tighten at the end of the cable.

You can effect an ECM reset by disconnecting the battery for 10 minutes. HOWEVER, then you have to reset the antitheft and alarm security system. You will need the code for your radio, and you will need to a full Drive Cycle relearn. https://www.google.com/search?q=2003+cadillac+cts+security+system+reset and after that it still might not work. You really need a mobile auto electrician with a pro grade scan tool computer. You issue is electronic, not mechanical. https://www.google.com/search?q=mobile+auto+electrician+near+me ....
