Has anyone replaced the ambient temp sensor on a 140 style benz? How hard of a job is this? Mine is jumping all over the place and I think is affecting the climate control.
Thanks in advance.

 

just yank out that small grill on the front left bumper where it is located (start from the top).

 

What year 140? I think the early ones have you replace the the sensor with the wire (one piece) which is not a big deal, requires a little more work and a little more time. The newer ones have a connector at the sensor.
I may be thinking of the 129 though. It's been awhile since I've done one.

 

It is a 1992 300 sd. I'll try to remove the grill and have a look. Thanks
