Hi all, my 99 E300 lost AC last fall and being the type of person I am, I put it off until it got warm again. I believe that the reason it went was overpressure. On hot days my car's coolant temp goes up to the 100C range when not moving, and I believe that's due to a failing fan clutch which will also be getting replaced in this round of repairs. I've never repaired AC before so I'd like to do a sanity check before ordering parts. Here's the codes I've pulled from the HVAC module:

• B1227 Outside temperature indicator temperature sensor
• B1235 Emissions sensor
• B1241 Refrigerant fill
• B1419 Electromagnetic clutch

It failed last Sept/Oct when idling in a parking lot on a 90F+ day and given the compressor clutch went and it's calling for more refrigerant, my guess is the entire compressor should just be replaced. If this is the case, I'd also be replacing the reciever/drier, expansion valve, and doing a flush on the system.

Is there anything else I should replace while I'm in there? Hoses? Condenser? (Please don't say evaporator )

A/C gurus, please let me know if my line of thinking makes sense!
