Hi Jim,

It is great to have you chime in on this. My friend's W210 has that kind of access to all kinds of information. The W124 does not have that available, as far as I know.

I also have a friend that wants to play with a slightly different resistor in your cool harness, to see if he can get the high-speed aux fan function to turn off at normal driving temperature after it kicks in. It may come on just a bit higher than 95 degrees, but still just short of say 100, so that the fans will still prevent excessive heat, but will also turn off when the car gets back down to 90 degrees. Right now, on a very hot day, my high-speed fans do not turn off after they come on with the cool harness V2. I think I still prefer that to seeing 105 degrees, but I also think I am interested in maybe just a slight tweaking of your cool harness. Maybe a resistor that kicks in a 97 or 98 degrees would let the things turn off. As I remember, you had a 97-degree cool harness in the old version. Did that one allow for the fans to turn back off on a very hot day, so it cycled more like with the stock system?

Thanks for the information Jim,

Ken

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
