My DMC aircon system had been put under great pressure... 500psi I think. A
faulty connection in the relay compartment meant that the cooling fans did
not come on when the compressor kicked in which caused great strain on the
system. Once fixed all seemed fine after being regassed and I had many a
weekend of ice cool aircon, but then, suddenly nothing.... turned out to be
empty and when nitrogen was pumped in to find a leak the high & low and
pressure switches were the overiding culprits which had failed.
Having replaced both switches at least one more leak remains. The rubber
hose which outputs near the high/low pressure switches when covered with my
finger shows that some airflow is coming through from the evorapator
assembly.
How do I get into the evaporator assembly as the screws if I remember
correctly need to be done from above and the workshop manual is not very
helpful on this one....
Can anyone help me on this please??
