Yes, the fan motor sitting upside down with the top bearing open allows for a drip of machine oil to be applied once a year should keep it moving freely for years. All good to keep things flowing.
Sounds like on yours Frank with it not working on fast speed the resistor could indeed be completely ruled out as at fault. Switch contacts likely culprit as you say. It's a slightly different way to do things that often used on other cars, the motor gets 12v supply when ignition on and the switch operates the earth. Fan speed 1 puts the earth connection through to the brown wire which feeds through the resistor to the opposite end , back down through the double wired connection and onto the fan motor completing the circuit. Fan speed 2 sends earth through the green/brown wire along the short route of the resistor and down the double connector and onto the motor. Fan speed setting 3 just sends the earth from the switch up to the resistor but as it's the double connector wire it just goes directly to the fan motor so runs at the full 12v without resistance. If you have continuity in the wire connection from the switch to the double connection at the resistor then that rules out a broken wire so hence the switch at fault. As I'm sure you have deduced Frank, not wanting to teach you how to suck eggs just wanted to try and explain the checking process so others can self check things methodically as there's no better feeling than being able to repair your own stuff
Good shout too on the rear window rubbers to make sure of a good seal. Before all the interior trim goes in I'll check them. I did clean and check the seals for damage before fitting. I'll check to see if they are applying decent tension. If not then a good solution would be to make a spacer gasket out of plastic or maybe some neoprene sheet as I have some for making spacers or gaskets where needed, a rubber spacer a couple of mm thick under the rear latch would pull the glass tighter by the same amount. Similar set up on AlfaSuds I've had before, they sometimes didn't go over centre quite as firmly as these do which OK it kept tension on the seal but also I've known them to pop open, not good for security or sealing !
That's it for the jobs for a little while, until after Christmas anyway. I have some time off work between Christmas and New Year though so should have the car completed in that week. Not really that much to do now as you can see. Front wings & bonnet to fit. Bumper o0nce I've cleaned and treated it, good tip Frank
I did take the rear lights out and do the rea one which looks much better. Some of the thick floor padding needs renewing but I already have some new self adhesive sheets waiting to be cut to suit and fit. Wiring is all done so once I know everything works then the carpet and seats can go in, probably makes sense to fit the roof lining back in before the seats thinking about it..
Once on the wheels I'll take it over my pit and tighten all the bushes so they are tight with the car level to prevent twist up damage. A good clean then as it's getting pretty dusty!
I do though have to sort something with the aerial if you guys have ideas. The car has never had a radio fitted and although the hole is there in the roof and an aerial cable is fitted there is just the base that clamps to the roof skin, no aerial mast itself. Can the mast be found separately? I did buy a roof mounted one without thinking about the mounting hole size which is quite big at about 18mm. Does anyone have a spare mast that screws into the roof base maybe? Or know where I can find? I'll have a search in the usual places a bit more, what I've found so far hasn't worked.
