Recently took the SL out on a long road trip.
Temp gauge sat at 80 +/- on the road.

In traffic it bumped up just above the line between the 80 and 120, I'll assume 100. Came down some when I started moving again.

I checked it when I arrived, still close to that 100 mark, but no aux fans running. Fuse is OK.

Searched here, not a lot of 129s with temp issue's.
Did see one that made me think they only run with the A/C.
Note my Climate Control is almost always in the EC Mode.
A/C kind meaningless if you never drive with the top up.

OK ??s
Will the fans run w/o A/C Running.
How can I check their operation ?
Where is the sensor and relay ?


Thanks
