Easy to replace. Done both of my Toyota’s fan motors. The fun part is getting the correct motor. If you just buy the one off Amazon for $35-40, you’ll find that your fan motor switch will heat up and you’ll lose Medium speed or something like that.
Get the right part. Also, while you’re...
RAT-TLE-CAN!!!
Hell, the hard part is the prep - taping off the windows, removing the trim, lights, etc.
Then go get your choice of color spray-in Bedliner at the parts store.
I’ll help if you want, just pick a Saturday before it gets too hot.
