Hello everyone, so I have a 2001 s430 and recently the ac started acting weird. It now only blows cool air from center and vents and hot air from all the other vents. I've tried looking up the problem but every thread I read the never fixed the problem. Please help need ac to work live in Las Vegas where the heat is 120 degrees

The problem you are describing may be a duo-valve. Here is a link about it and its replacement:

Thank you I'll check to see if this is it

I have a 2000 S500 with similar symptom. Mine turned out to be low on the refrigerant. Had the system evacuated, dryer replaced, and system charged - so far so good for almost 2 years now. You may want to check your refrigerant level.

Thank you so far no luck on fixing it the refrigerate leave is fine. Also check the duo value and that's not the problem either
