Well my compressor grenaded last night on the way home from the airport. It was blowing nice and cold and all of a sudden got warmer and warmer.

Got home pulled the codes it was B1419 electromagnetic clutch failure. After some searching figured out that was the seized compressor protection - if the compressor seizes the thermal fuse blows and releases the clutch and sets the code in the CCU.

So I went out this evening and tried to spin the hub. No joy, locked up tighter than Went over to the 124 and double checked I was grabbing the right thing, sure enough that was it.

Pricing up a bill of materials now
Compressor
Condenser
Evaporator (pretty sure it was leaking)
Expansion Valve
Receiver dryer and the temperature and pressure sensors
O-rings

Any suggestions or hints on the job? I have a non travel week coming up in a couple weeks so I plan to take off that week to fix it.

I have watched the you tube video by the guy in Taiwan tearing out the dash/front cowling for the 210 and this does not intimidate me at all. I have had it about halfway apart before and the thing goes together like a giant 3D puzzle. Looks to be a lot cleaner than a 124 dash which I can do in my sleep.
