I have a 06 C-50 with 5 K miles and after a long trip double up the other day my radiator fan is not coming even in stop and go traffic 90-degree day.

I checked coolant level in the reservoir today and it was a little low but nothing very serious.

After the long ride the other day when we got back home I noticed that the idle was rough also.

I found the fuses but I could not get the fuse lid off, must be a trick to it.

Any one know what color the wires are to jump a hot wire from the battery to check the fan to bypass the switches ans eliminate one item at a time.

Any ideas would be great.
Thanks Rod
 
The temp sensor is at the bottom center of the back of the radiator. Disconnect the two wires at the connector, and jump across the two terminals. The fan should come on. If it does, replace the sensor. If not, the problem is somewhere else.
 
There was just a post on this just a little while ago on the M50 board. My fan came on maybe 2 times since I have owned it, riding in the summer heat. You can check you fan as described above, I bet there is no problem.
 
A few weeks ago it was about 80 and I ran the Suches loop. Took the 60 then cut across Wolf Pen Gap then back down the 129. This is mountain roads with lots of twisteys, and elevation changes, I gave it a good run, non-stop and my fan only came on once.
