Before Installation - Mercedes-Benz Automatic Climate Control System II Installation Manual And General Information

2 of 20

Before Installation:

-My installation took about two hours to complete.
-Ensure that all fuses are in good condition, and not corroded or knocked out of place.
-You'd be surprised how often a faulty fuse causes the whole system to fail.
-Start the car and cycle through every climate control setting. Make sure any of the issues
present in your automobile are not vacuum leaks. If your climate control system is not
functioning properly as a result of vacuum leaks, this will not solve your problem.
-Before working under the hood, ensure the car has had plenty of time to cool. Make
certain the vehicle is in park with the emergency brake on. Also, disconnect the negative
battery cable to prevent any electric shock or shorts.
