Volkswagen Santana heater fuse location, where is the Santana heater fuse?

The fuse of Volkswagen's new Santana heater is in the fuse box, numbered OE, as shown in the figure below. If the heater fails, you can check it according to the following steps; 1. Check whether the connecting plug of the heater line is loose. Find the plug, pull it out and insert it several times, and wipe off the nourishment of the contact head piece to achieve good contact. 2. Check whether the heater fuse (chip) is deformed by heat, resulting in poor contact. 3. Contact heater relay is intact or loose. 4. The problem is more serious. Wear of bearing and sleeve of heater motor leads to friction between rotor and stator, but the possibility is relatively small. Please check the item 1.23 first. If not, check item 4 again. The problem will be solved.
