To be honest, I would rather just bought a 99-00 civic if you want it that bad. First, you need to remove the whole entire dash. You end up unplugging like seriously 30 harnesses (and then at the end get to play a guessing game and figure out where they all go!!!). Then once the dash is out, you have to remove the heatercore and blowercore. You have to remove the entire exoskeleton of the dash to replace the directional vent behind the climate control. Put it alllll back together. Recharge your A/C Much easier said than done. Takes a day or two, depending on how long you work on it. The parts you will need are:
99-00 climate control $85-120
99-00 direction vent $100-150 for everything else
99-00 heatercore (full assembly)
99-00 blowercore (full assembly)
99-00 heatercore harness
99-00 climate control harness
A/C recharge kit
If you were asking how much for my cubby, $14 shipped and it's yours.
