Hi, I just recently purchased a 1998 S500. I can't seem to figure out how the a/c (climate control) functions with all the buttons. Ex: When I'm driving the a/c is on then the fan turns off for a little bit then truns back on. How do I just make it work normally? There are soo many a/c buttons like the blue and red one on the center vent. I just need some guidence in this matter.


Thanks.

Sounds like you need an owners manual.

The blower issue is most likely a problem with the blower regulator.
