Seat Leon FR, air conditioning works, then blower stops. Increase temp blower works, I can then slowly decrease temp and "chase" the blower. Have changed external temp switch. Cannot for the love of god find the evaporator temperature sensor (G308), the instructions are so vague, can any one please provide a video or better diagram so I can change it.
 
Are you certain it is not low on gas? I had these symptoms: a/c worked fine for the first 30-45 minites of a journey, then airflow from vents would stop almost entirely. A/c would then work perfectly later on after a rest. No fault codes. A halfords free a/c check confirmed low gas, and it worked fine for after a top up.

I believe the evaporator can freeze up when the system is low on gas.
