Hi All:

I especially hope Jim F and MBDOC see this post...but I will of course accept all help from everyone (thanks in advance)...

I have a 1995 S320 W140 bodied, M104 engined Benz. I had a minor overheating issue on Sunday which resulted in a small t-connector near the firewall breaking and spraying coolant out. I stopped the car and opened the hood and let it sit until the tow truck came - did not lose too much coolant. I towed it to my favorite indy shop and he replaced the part and hoses and topped off the coolant. The car now runs at 90-95 degrees C consistently (very nice).

One big problem, the electric fans only come on at 105 degrees C. When I put the A/C on, they do not run at all. I have read about the pressure switch behind the driver headlight on other posts - so I checked the a/c pressure and it turned out OK, but I still had bubbles in the glass sight. So I did a minor recharge and the bubbles are now gone (yeah).

So, the electric fans are still not coming on when the a/c is turned on. I was not sure if there is a magic relay or a way to "jump" the fans to have them come on (Jim F, are you reading this?)

Any steps to solving this problem would be appreciated.
