Battery/ Electrical Recharging Problem
 

I have an 01 C320 - In the past year I have replaced an alternator, and a new battery in 2/06 and again in 7/06. My battery will only hold a charge for 1 day unless I drive long distance, the charge may then hold 2-3 days if I'm Lucky!! Is there anyone that has any advice or suggestions that could help me resolve this issue. Also about the time I started having these problems, my AC seems as though something is block the vents, not cooling as well, and blowing harder than normal with very little air blowing from the vents. I don't know if these items are related, but I would appreciate any feedback.

Thanks,
Ronnie

check charging system.

alternator belt must be in good tension.

Yes, what Sleepwalker said. The alternator is either not charging the battery properly or the charge from the alternator is not getting TO the battery, which means a bad cable or cable connection to the battery. If the alternator belt is loose or slipping, there you go. The A/C problem is most likely linked to your problem as well. A simple check of the charging system with a meter will tell you what's going on quickly. Let us know.;)
