Hi Folks - I could really use your help!! I am experiencing the same
problem with my 97 E420. The engine is running very hot and I think
that it is causing the Air Conditioning to malfunction. It is a
similiar problem (I believe) to what Laforzaprop has been
experiencing! The air blows cold at first - then when the car heats
up - the air blows warmer and the system seems to shut down? You can
hear almost a hissing sound in the system and it blows warmer more
I don't think that my auxilary cooling fan is operating properly
either?? Is there a relay or fuse for this fan that anyone knows of?
ANY help that you guys could give me on this is REALLY appreciated! I
have another appointment on Tuesday to try and diagnose this problem
and it is stumping my mechanic! Thanks again folks!!
