124 "porcupine" question
 

Dear Listers,
Could you please share whether all 124 "porcupines" are created equal. I am strongly tempted to replace the one in my 87 300D (240KMi) with one from a 1994 500E (64 KMi).
Your suggestions are highly appreciated.

Translation, please.

The porcupine is the blower motor fan speed regulator below the wiper.

Actually, its just a heatsink for the regulator, which is a small circuit board on the underside of it in the middle. But, MB only sells it as one part.

I do not know of interchangability of it with other years.

HTH,
