Hey guys,

Long time no see. I previously had two w203s (at different times), but I recently bought an 06 e500. I noticed a weird issue during a long roadtrip i did yesterday. I drove 750 miles from Kentucky to New Jersey. During the beginning of my trip, the AC was working fine. About 500 miles in, I noticed that the AC was very weak. It was still cold, but there was barely any air coming out, even at the lowest settings. I did some searching and thought that it might be the blower and/or regulator or maybe even the duo valve, but this morning when I started the car, the AC was working perfectly.


Based on my searches, I think that it is the regulator but I figured id ask the experts of MBWORLD for their opinions.. Any ideas?

If you have climatronic with REST button, you can read the sensors for troubleshooting right on it.
If not, read them with SD.
Read parallel topic about climatronic options.

No, my E500 doesn't have a REST button. By SD, do you mean Star Diagnostic?

I'll look up the topics on climatronics options, thanks!
