Air Conditioning with a mind of his own !!!!
Good Afternoon
The AC in my 2004 E320 is driving me crazy.
All the lights in the control panel work properly (change in intensity, AC on, direction of flow), but the $#$@% starts and stops whenever it feels like.
To make matters worst sometimes when I turn off the car the blower still keeps running for about 1 or 2 minutes..
It's 91 degrees here in Miami most of the days and I really need this working.
I wonder if is just a matter of refrigerant level or the regulator?
In a visit to my indie shop (ex MB Mechanic) they hooked the computer to the OBD Port and they tried to control the AC with no avail. It showed full blast but was dead.
Please Help !!!
Thanks

It was a bad Blower Motor regulator... and it was a very common problem.

Feels good to save yourself money, doesn't it?
I suggest you also go ahead and order yourself a (Bosch) Crankshaft Position Sensor from the same place you ordered the blower regulator. This way you have it on hand when it craps out, as it's just a matter of time before it does.

Will Do, thanks for the suggestion.
Now that you mention it,the ignition is beginning to act up. Sometimes When I turn the key I hear a click and then nothing, I believe this is exactly what you are talking about.

When my CPS failed, it presented as a normal crank no start codition. Leave the car alone for a bit to "cool off" and it cranks and starts normally. You may detect a stumble in the idle while waiting at a traffic light too, before it really fails.
