I own a 2002 CL500 and have been having battery
problems. My battery runs completely down after two days unless it's driven. My problem began when the trunk motor failed and as a result the trunk didn't seal properly in a rain storm. I had the Benz dealer replace the trunk motor, which allowed my trunk lid to seat and seal properly however the battery continually runs down as mentioned. Today I replaced the battery with a new one and when I did I inspected the newly installed trunk motor. It sits underneath the battery, with a cap over the cavity between battery and trunk motor and is housed in a sponge like holder (the part number on the sponge like holder is A21580000135). The sponge cradle for thhr trunk motor was completely soaked from the rain that entered due to the trunk problem. I removed the motor, pulled out the sponge like cradle and noticed that both the positive and negative terminal on the trunk motor were in constant contact with the wet cradle. I assume that this is effectively causing a ground condition, so after I did my best to dry out the cradle I placed a piece of thick plastic between the two terminal and the sponge like cradle, then put the cap over the trunk motor and then installed the battery. Do you think the wet sponge like cradle making contact with the two terminal on the trunk motor would cause a ground that drains the battery? Do you think I should do something else in addition to what I've done?
JA: Is this your first time dealing with this issue?
Customer: no the dealer has been trying to figure it out for weeks, I have become frustrated with their service, they should have noticed the sponge like cradle was sopping wet when they replaced the trunk motor. This car, although a 2002, has only 31k miles. I am the original owner.
JA: Are you hoping to fix this yourself? What have you tried so far?
