W210 A/C Compressor Fuse?
 
Hey guys,


So I went to get our E430 charged today, but the guy told me that the compressor isn't engaging, and the system is full.

I decided to give her a look-see, and I cannot for the death of me figure out which fuse the compressor is on, if any.

Closest I've got is Fuse 4 and 7 for the auto climate control and blower motor, but the controls and blower do turn on.


Any help or direction is immensely appreciated (a rebuilt compressor costs 500ish bucks :eek: )

Also don't know if the clutch could be stuck or the relay is shot; any idea where these are located so I can check it out?


Thanks,


Carlen

Do you have the pushbutton unit? If so, you can extract trouble codes without additional tools.

There is a thermal fuse in the clutch which cannot be replaced. I don't know which other fuses run the AC system.

How do I pull those codes?

It's my mom's car, so I haven't really investigated too much into how to fix things...


Thanks,

This is amazing; I wish I could do this on my W126...

It's giving me B1234, which is the sun sensor; I assume thats the sunroof temp sensor?


Thanks a billion,


Carlen

Nope, I did more searching and its those little lobes on the dashboard...

You can safely ignore the sun sensor code. Is the EC lamp on?
