Trailer wiring uses the fuses for the car lights. Turn signal, running ans brake lights. Some plugs also charge the trailer battery if so wired. Check the ground wire for a good body connection. This wire often gets overlooked and can stop all trailer lights if it fails.

The modules need to relearn the conditions it operates under. Take both battery cables off and touch them together for several minutes. Reconnect and start the engine. Drive the vehicle 20 or more miles in city traffic. That will relearn the modules.

Cruise control will always disable itself when any CEL light is present, so that's normal. The Stabilitrak light problem is a known common problem with these. Your steering wheel position sensor needs to be replaced. Mine does it every morning IF my steering wheel wasn't put into a straight position when I parked it. Straighten the tires, turn the ignition off and restart. Light will go out.

Get filter changed is always your first fix with shifting problems in a automatic transmission . They wont tell ya that but it usually is the problem or a shifting solenoid that can be replaced at same time..

sounds like electrics issue. the heater fan should be connected to the ignition switched circuit, not the constant power circuit.

if this is not resolved it will cause your car battery to go flat if fan is left on.

sounds like you need to take this to a garage to sort
