If the cooling performance of the air-conditioning system in the above-mentioned vehicles is unsatisfactory, the installation of an air diffuser and an additional cable with resistor (for the evaporator temperature sensor) can remedy the situation.
When outside temperatures and humidity levels are high, inadequate cooling of air can occur as a result of unfavorable flow conditions. The evaporator then partially freezes up. This can be triggered by a negative characteristic of the evaporator temperature sensor.
Proceed as follows to rectify the problem:
Assisted by the additional diffuser, the air flow inside the evaporator box will be optimized, thus bringing about an improved cooling performance.
Installing a cable with resistor alters air-conditioning control and prevents the evaporator from freezing up.
