no, the pink fuse is the AM2 fuse, you want the 30A RDI FAN fuse in main fuse compartment under hood

Is the fan fuse below the driver side headlight as shown in this thread?https://www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/91182-no-more-overheating-a-c-fan-works.html

what is shown in the pic below is the case for the RDI FAN relays

the RDI FAN fuse is in the center of the main under hood fusebox

either these RDI fan relays below the headlight, or the fuse could be the issue
