Fan was not working, I put direct power on to it, nothing. Replaced with working one. Also noticed there was no fuse, so I added a fuse. Tested relay, working. Tested new fan in car, working.

However I had the a/c system on and it was not kicking it. It is not that hot outside and my system is topped off. If I leave the system on full bore will it eventually come on?

I'm trying to decide if the tempature switch is bad or not, I really hope not. On the mercedes service book it says:

Temperature switch in receiver dehydrator.
"cutting in point - 52degrees +- 3degrees"C
"temp. tolerance: 7degrees - 12 degrees"C

Can someone please elaborate what this means and assist? Thanks for all your help in the past.

Marco
