There's a coolant leak somewhere in the LS's engine (already checked water pump, thermostat, degas bottle, and thermostat housing/cover) and causes the car to overheat everytime I try to use the AC. So the past 2 weeks I've been riding with no AC. Yesterday I was removing the radio/climate control module to set up some speakers and since removing the control module, the AC is constantly on with no way of being turned off. The lights on the module only come on when the panel/floor button is pressed but no options to turn off the AC. Any suggestions? temporary fixes are welcomed
