System Performance Test?
1
Refer to the instrument panel outlet air temperatures
recorded during the A/C system performance test.
2 Does the discharge air temperature between the right
and left center instrument panel outlets vary by more
than 1-2°C (2-3°F)?
Did the customer mention that the A/C system output
3 temperatures are good at first, but then turn warm
during extended drives?
