Does replacing the Thermistor on the evaporator or the Trinary Switch require evacuation of the system? Is the A/C amplifier the same as a relay?

I'm saying yes.

Thank you for your response. Just to clarify, is that a YES to both questions?

I'm not 100 percent sure on that one. But I believe the system will need to be reclaimed when using that switch. I checked and I don't have one in stock to check to be sure.

Thanks again.

Is the A/C Amplifier on the illustration the same as a relay?

There's no valve under the switch like most American cars have. The refrigerant must be out before unscrewing it. Looks like the evaporator case has to be taken out of the car to reach the thermistor. That would also require reclaiming the refrigerant before disconnecting the lines.

The A/C Amplifier is a little computer that looks at readings from the thermistor and other stuff to control the A/C. I think the amplifier drives seperate relays mounted under the hood.
