i originally was checking why my climate control wasnt cooling.......which led me to the rad fans......which don't seem to come on at all!

but they don't seem to have fuse's associated with them....or appear in vag com.

anyone any idea how to check fans are working?

thanks in advance.

o yea ..it's an octavia 11 tdi

There's another fuse block under the hood (sorry, bonnet), right next to the battery. Check those as well.

Also look for a rodent chewed wire in those cable ducts leading to the radiators.

actually i removed water temp sender..and fans came on at high speed..so thats working...

don't come on at low speed......when i turn on a/c.......

switch is a good bet.

which switch?thanks

I think it's probably the sensor gone wacky.
