dont know about the blue tape but ive read that the passenger blend motor has 5 wires if that helps
if you havent got a/c you can just take out the glove box to get to it. if you have then like me its off with the dash, lucky for me i need to replace the dash on mine anyway, so it'll be 2 birds with one stone
found a guide on another site but dont know if you are allowed to post links on here
