Santa Fe 2004 Automatic Temperature Control
 

Has anyone experienced this issue with the ATemp

ie: warm day80's. after car sitting not used.

When automatic system, kicks up the fan, it does not idle back down
effectively. It tends to run high/faster then it needs to. Either the logic
for the system is not programmed at the right points, or the temperature
sensor in the car is not providing good feedback. Most times, we must
manually reduce the fan speed by several levels, thus circumventing the auto
feature we expected.



Note: I have had several cars with automatic temperature controls..this one
seems to have poor logic or sensitivity.

This vehicle has a sunload sensor, so on hot days in the sun, it may keep
the fan running faster than you expect.
