Toyota Prado 120 A/C Leak and Evaporator Replacement explained

Recently a customer contacted me about their Prado A/C to find a refrigerant leak. The car had been regassed previously, and lost cooling performance again over 2 months. The evaporator was corroded and needed to be replaced. Sometimes this type of leak is accompanied by a smell from the A/C ducting when the A/C is first used in the morning.

This is a major job on the Prado with DUAL ZONE CLIMATE CONTROL ( LCDs with driver and passenger temperature ) as the dash needs to be removed: the HVAC unit is split in the centre and needs to be disassembled outside the car.

Please note that the Prado with MANUAL A/C Control ( one manual dial for fan speed and one for temperature ) is easier and cheaper to replace, here the evaporator can be replaced through the passenger footwell.

There is some misleading information out there, please consider what type of A/C control you have when getting quotes for this repair.
