OK. You have a Landau, i.e. no rear windows and no rear windows lockout switch. I incorrectly assumed you had a coupe with the two powered rear windows.

Keep us informed as to your progress.

With four windows, you don’t have a landau. So there are actually five switches on the switch panel – four for the windows and one, a rocker switch at the top of the panel to lock out the rear windows from being controlled from the switches at the rear seats. If you have power front vent windows, th...

Would you please elaborate on your post? What circuit did the fuse you replaced protect? The power windows are not fused – they are protected by a circuit breaker. From what switch did you pull the connector? Was it the little rocker switch at the top of the window switch plate? It’s also unclear wh...

The wire to the oil pressure sender is more or less on the driver’s side of the engine compartment – the power window relay is more toward the passenger side on the firewall near the hood spring I think. I recall it’s the only relay there - unless you have a convertible which has a top relay on the ...

And there's the window relay on the firewall that may be bad. You can temporarily, or permanently, jumper it to see it if things work. The windows are powered via a circuit breaker - also powering the horn and power seats if installed. If they do not work, it could be the breaker that's bad. althoug...

It’s great to hear your problem is gone. But it’s not clear, to me at least, how allowing more rheostat travel solved the problem of some normal and some dim bulbs. The rheostat is the single, initial power source to the bulb wiring circuits. So doing something to rheostat should not have altered th...

You are correct about the Seat Belt light not running thru the dimmer – if it did it would only be illuminated when the lights were on – but it’s on with the lights on or off. No doubt a new harness is the nicest fix, but few of us have the $, skills, and time to install one. And a jumper may actual...

It’s surprising to me that the instrument/speedo lights were properly bright when you put 12V to one of the glove box wires – UNLESS you also had the head/parking lights on also. That is, whatever is causing the console lights dimming with the power coming in from the dimmer, should also cause the s...

If several bulbs are dim, you can likely rule out a bad ground because the bulbs are grounded at different locations. The radio, heater control, clock and washer/vent, ash tray and glove box lights are grounded individually at various points so it’s very unlikely all of the grounds are bad. And as p...

Anyone with a 66 experience the ammeter not working? Mine does not - the needle stays in the zero position. A voltmeter says the alternator is working, i.e. the voltage moves up when the engine is revved and the headlights are on and the headlights brighten a bit when revving from idle. Could the re...

Until your Osborne manual arrives, here are some things to play with. My 1966 convert has the same colored wires to the 20A breaker as yours – one yellow and a combo with a yellow and red/blue stripe. 1—Disconnect both connecters from the breaker and use a multimeter or the like to check the resista...

When trying to retract/lower the top, the left side deck open limit switch (by the left hydraulic cylinder) is supposed to stop power to the lid opening cylinder pump when the lid is fully open and then pass power to the raise upper panel motor. If this limit switch is “way” out of adjustment, I sup...

Drive using the big dot, but the tranny often starts in second anyhow (see tranny issue below). And no black stuff out of the tail pipes. Also, the rear end is still 3:1 as far as I know, but a PO may have changed it. I’ll soon be pulling the plugs to check them and the compression, and look at the ...

I’m getting about 7 MPG on my 64 390, mostly in the city and not jumping off the line. I expected to get about 9 – 10 MPG, so the 7 MPG seems really low. Using premium gas, and cannot find any leaks, i.e. tank to carb. The air cleaner filter looks clean (white). The car idles smooth and the auto cho...

I have an intermittent tranny shifting issue in my 64 convert. With the selector in the big dot (city) and starting to move from a stop, it will sometimes shift into low – 2nd-3rd OK as it should. But sometimes it will start in 2nd and then quickly downshift to low and then progress thru the 2nd and...
