I just picked up a 1974 1.8 (carb conversion). It has been parked in an unheated garage for about 3 years, and was supposedly running fine before that, although it wont' fire up now.
My plan is to get it running, drive it on nice summer weekends, and use the other 9 months of the year to fix it up. Never worked on a car before, so looking forward to joining the fun! I'll post some pictures as soon as I figure out how... |

I now have my washer wired into a pushbutton switch, and the wipers wired into a temporary toggle switch until I can source a new wiper switch. A bit of progress. I have no idea how the rest of you guys can accomplish insane amounts of work in a single day.
Next up is the defrost blowers. I am still confused about the whole heat/defrost system. I understand there is supposed to be a fan in the engine compartment that will push air through the heat exchangers. I also see what looks like two fans below the windshield -- are these the defroster fans? Do they run off a separate circuit and switch? |

I understand there is supposed to be a fan in the engine compartment that will push air through the heat exchangers. I also see what looks like two fans below the windshield -- are these the defroster fans? Do they run off a separate circuit and switch? There are a number of valves in the system that are controlled by push-pull cables, as well as the fans. The engine fan blows air into the heat exchangers. If the heater lever is pulled up all the way, the heater blower also blows air into the exchangers. The air gets warmed up, and then the "flapper valves" will either dump it out under the car, or will direct it into the hoses running through the longs. Those go up into the dash, into the distribution system. That uses valves that either direct the air down into the footwell, or up to the windshield. Those are controlled by the red slider on the dash. There are separate valves that control the fresh-air system. Similar to the hot air, the middle slider on the dash directs the fresh air up to the windshield or down to the footwell. The upper slider opens a valve that lets air in from the inlet on the cowl, and when you slide it far enough to the right it turns on the fresh air blower that lives up in the dash. (There's only one of those, BTW.) There are a bunch of bits, and getting the cables right can be pretty fiddly. But it's reasonably straight-forward in concept. --DD |
