At temperature 99–105 ° the C fan works at the second speed. If the fan does not turn on, pull out both wires from a thermoswitch and connect them with each other. Include ignition. The fan should turn on at once. If it occurred, replace a thermoswitch, and then inspect again.
The electric motor of the fan is protected by the fuse which can fuse. If a safety lock as it should be, check the fan electric motor:
