Radiator fan fuse keeps breaking
Hi,
second time in a month, i was driving in traffic and temperature went to maximum and red light went on. Pulled over and fuse nro 14
-cooling fans left-hand fast
Was blown, changed that and everything ok. What could be the reason that it is blowing this fuse?

When I worked at the dealer and had customer pay fan assy replacements due to one fan failing, I would save all the functioning fans and test them for operation and CURRENT DRAW.
The fans that exceeded 30 amps were discarded and most would read 25 amps while operating 12 Volts.
You might run each fan individually with 12 V and check current draw.
A 30 amp fuse will struggle to keep up with a 30 amp draw?
Jaguar sold the fans as a SET but they can be replaced individually.

so i started my car and put ac at max cold, and at least that fan that is visible on engine bay looked like it was spinning at max speed. It spins and then it stops and then it starts to spin again. Somekind of interval which looked like it is operating as it should.

You need to observe both fans. With the AC on, the fans should first start at low speed and, if the AC demand is higher (like max. cold, hot day), both fans should switch to high speed and, after some time, back to low speed. If only one fan is running and only at high speed, the other fan might be "dead" and this can cause the fuse of the running fan to blow.

sorry for delayed answer. Fuse 14 is ok, and fuse 12 has never blown. What would be the best way to determine where is the problem, my quess would be that problem is in wires.
