2000 Mercedes-Benz S430 Q&A

2000 Mercedes-Benz S430 Question: problem with the air conditioner. Will not maintain a cold condition.

Air only comes through the center vent. The blower is very loud but does not cool the csr. -
Answer 1
make sure cabin air 'dust' filters are clean.. use 'auto' and make sure side vents are not closed other than that i would have to see what MB diagnosis codes were stored.. but first of all i would disconnect battery for 1 min then reattach and see if system fixed itself.. ( dont laugh it has fixed many 00 and later MB's for me) -
