Where is the cabin air temperature sensor that the climate control system uses on a 99 E300? Is it up on the rear view mirror? I think mine may need replacement. Thanks.

It is in the dome lamp assembly, but you can replace it by itself.

Thanks MBDOC. Now where is the high pressure air condition service valve? The low pressure one I have found but for the life of me the high pressure side is hiding. On my ML it is near the condensor. Thanks.
