SL500 air vent problem
Question type: Maintenance & Repair
My 1999 SL500 has recently stopped blowing air out of the foot vent and the center vents of the system. Air and Heat still come out of the defroster and side vents. (the settings for the center and foot vents are set properly) What could be the problem?
Thanks Scott

You may have seperate blower motors for different vents. You could also check your fuses to see if one has blown.

Yeah, checked all the fuses, the Climate control unit responds well including diagnostics, it even registers the vents opening and closing when I do it manually with a screwdriver. I'm inclined to think it may be the Vacuum Valve actuator. which is what I am afraid of.

This turned out to be a disconnected Vacuum hose behind the firewall. Once I located the loose connection (small thin white tube) and connected back to the engine hose. Vents began to work after I started the engine and ran for few minutes.

Scottc, I have the identical problem with my 99. Could you be a bit more specific as to the location of the thin white tube? Thanks

Thanks Scottc. Found it and fixed it!!!!!

Glad you found it, probably saved yourself $200....I'm re-doing my convertible top in the next couple of weeks (getting all the parts and tools together), can't see paying someone $2k to do a lousy job (got the top on Ebay, and an installation video) looks easy but tedious, lets see how it goes...

Knowing my local M-B shop, I think it saved me a lot more than $200. Let us know how the top installation goes. Have a great summer, thanks again.
