Brothers of The Benz, All
Every year we all have the same problems.
There are those of us who had problems last year and corrected them; and now we are here to aided those who are where we were a year ago.
The early W124 Automatic Climate Control Air Conditioner is at it's time in life where the major components are in need of replacing.
The problem is made worse buy converting refrigirants.
The compressors have over 150,000 miles, the blower motor is at it's life end, the x-valve is lazy not to mention lines and hoses.
We want our technicans to flush the compressor and evaporator coil of old type oil. Have you ever seen the evaporator coil?
It's configuration is such that flushing is almost an impossibly task unless you remove it from it's housing.
If you have disassembled to this level you should replace everything inside the housing.
Too high head pressure or too low suction pressure.
Condensor full of bugs?
I bite the bullet and had my A/C completely rebuilt.
Both the high and low sides. Compressor/clutch with it's electronics, drier/reciever, x-valve, evaporator coil, all the vac-elements, resealed the evaporator/heater housing and a complete blower motor fan assembly, and convertig to R134A.
It doesn't cool as well as R12, but with the thermostat at 22C, the fan speed slows and when it isn't extremely hot here in Houston, the clutch cycles.
I probably spent more than my 1987 300E is worth; but having bought it new and maintained it as well as can be expected and after 14 years of faithful service she deserved it.
This will be my last car for at age 66 years it is more than I need.
You are right, Prince Phillip of Fastlane is super.
Happy Trails Beep Beep from The Spiderman in Houston!!!
