Checking the refrigerant
Check the level of the refrigerant and that there are no leaks in the climate control system.
Remedy as necessary.
Note! Always disconnect the battery lead when working on the climate control system. See Battery, replacing Battery, Replacing.

Was a fault detected?
Yes - Verification
No - No Fault Found
-------------------------------------------------
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
Note! Wait at least 1 minute before "Ignition on". This is to allow the climate control module (CCM) to carry out a new diagnostic.
- Reinstall the connectors, components etc.
- Ignition on
- Read off diagnostic trouble codes (DTCs).
The fault is no longer present if the status of the diagnostic trouble code (DTC) has changed to intermittent.
