The upper passenger side firewall has a little black line passing through it . Usually it is broken. There is also a ball on the drivers side firewall behind the hinge
either a vent door actuator is failing or vacuum,,,or the ac is heating up cause of resricktion in ac system ,or fans are not working and ac is heating up
you may want to check on the radiator fan. The AC has its own fan and once AC is on, the fan would help bring down the temperature. It is either the fan is not blowing or has become weak. You can check on the fan by pulling out the temp sensor on the lower radiator hose. The fan should blow at full speed when doing this.
Check on the water reserve the water inside it goes down, if not there may be a leak somewhere. Water vapor may be escaping and lessening the effectiveness of the cooling system. This may be a reason why the engine cools down after the AC fan is on.
