Weak-*** Air Conditioning!

Hi All -

It seems my A/C is really weak. System has full charge, but takes forever to blow cold. Also, passenger side is less cool that driver side even with same temp setting or on coldest. Any thoughts or is this just what is to be expected from a 2004 Sl55? Car is a huge heat sink and I am sure the black interior doesn't help.

John

Try the reset first. We just replaced the AC compressor on our ml63 with the same symptoms.

Mine felt also weak in my SL65 this hot summer. But when I researched a little bit I found sources that it is only ventilation in the seats NOT cooling from the A/C??? Some said it is suclking the air out not blowing it into the seats. Can anyone confirm?
