B1419 is the code for the electromagnetic clutch. Yes, that will prevent compressor operation, but usually it wouldn't operate anyway.

Check the wire going to the compressor to ensure that it is not damaged. Sagging engine mounts can stress this wire. If it's connected, disconnect it and measure the resistance between the connection on the compressor and ground. If it's open, your electromagnetic clutch is indeed bad and you probably need a new compressor.

I have read about 1000 post. 1 of yours you said to try and free spin the front side of the compressor with the engine off. You said that it should have equal pressure on the H and L side if it's cold. I will try this in the morning. I tried a while a go, but the engine is about 90c. I did make somewhat of a go at it. I think it's seized probably why I have B1419. It has been running fine but I have heard that low fill hiss from time 2 time.

What is a good price to get a new compressor? What else should I change out while the system is apart. Sensors or hoses? You change hoses with age or when they leak? All my sensors read the same in the morning. I would hate to have it all back together and a hose or 40 dollar system take me out again. I have 110k on a 97 E300D.
I live in AZ and the system is running 10 months of the year. I don't know if I have ever had the heater on before.
I would change out all the gear myself, but I don't have all the A/C gear to set it up properly any way. I should I expect to pay in labor?? Or all in?? 3K
Would it make sense to have it evacuated, then change all my parts out, and then have them fill it and set it up? Probably makes more sense to pay out the labor and have them stand behind it if some part or issue arises.
I was hoping that the evap sensor was the issue, as so many have had that issue.

Could it be just the clutch? I will ohm it out in the morning.
