I started driving it to work and realized the ventilation system didn't work. I couldn't turn on the fresh air fan and the heat wasn't hot. I figured the heat was due to the cables from the heat tubes / exchangers not being hooked up. The fan though.. ugh. Of course it's WAY inside the dash. So I started taking stuff apart.. and a few hours later... The air box comes into view: A short while later it's out: Notice the nest coming from the main air tube to the rear of the car. On the ground I had to take apart the box. It has all kinds of complicated flapper doors. Removed the old fan and put this new one in: Later I had to replace the switch too. I cleaned everything up: Re-assembled. Re-installed. Of course half the gauge lights weren't working, the horn was dead, the fan still didn't turn on etc. Another few hours and the dash was all fully assembled and everything worked. Woohoo fresh air and a high power fan! Most these cars have dead fans if you look to buy one. Mine is the rare gem that actually works now.
