Territory Climate Control

Just yesterday after towing a trailer (empty) the entire Climate Control system shut down. When I start the car, all I see is the air recycle logo flash on the instrument panel (picture attached). No other information is on the screen apart from the radio and trip meter. I'm not sure what is wrong, as the A/C was working perfectly when going to pick up the trailer, and even on the way back. It just stopped working when I took the trailer off the back of the car, and drove the car back into the garage. I tried to press all of the climate control buttons to turn it back on and nothing seems to be working. I've also checked the main fuses, but they all seem to be OK also. Also, after removing the trailer plug from the car, coincidently the reversing sensors no longer work. Normally when the trailer plug is inserted, the reversing sensors are deactivated, but it would seem the trailer plug is still inserted.
