My 1976 Coupe de Ville has no warning lights (row on top of dashboard above speedo) except the generator. How do you replace the bulbs, the workshop manual is not very clear but suggests the whole dash...
Headlight switch bulb:--
The headlight switch will come out of the dash by pulling firmly
on it, you may need to twist it slightly, don't be too worried if it seems very
resistant to coming out, just pull hard!
Once you have the switch out of the dash, you can disconnect the
connector block from the back of the switch by pulling on it.
The next thing to do is to remove the bulb holder from the back of the switch,
you will see two small black plastic prongs , the easiest way to do this is to
use a long nose pliers and pinch the prongs together, then pull the bulb holder
out of the switch.
Pop in the new bulb , reassembly is the reverse of disassembly! if you have a problem getting the bulb holder
back in, you may need to pinch the plastic parts around the bulb to ease it in.
Clock and warning light bulbs :--
This is actually very straight-forward, first of all remove the
speaker grill from the drivers side, just two small torx screws holding it in.
If you look through the windscreen from the outside of the car you can see the
various bulb/holders (these come in one piece). Obviously you need to work out
which ones you need to replace. The larger ones near the top are the main clock
bulbs, and the smaller bulb holders a little lower down are for the various
warning lights. To remove these all they need is a quarter turn and they will
pop out.
Heating, fan switch, ashtray etc. bulbs:--
There are two possible methods of replacing the bulbs for these
components, if you have small hands and are very dextrous the easiest way is to
remove the stereo and stereo casing, then feel around for the various bulb
holders and replace the bulbs, if like me you think you will find this too
awkward, you will need to remove the kickboard/kneeboard, as this will give
slightly easier access. To do this follow the steps below:---
First of all remove the lower shroud from the steering wheel, 2 torx screws on
either side of the wheel and a large plastic screw that needs a quarter turn on
the shroud itself (under the wheel). Next remove the ashtray, then remove the
ashtray holder by removing the 4 screws and the centre 10mm bolt , you can now
replace the ashtray bulb if required. Once you have the ashtray holder out you
will see another larger bolt behind it, you need to remove this also.
You now need to remove the centre console, first of all pull out the rubber
between the console and the gearshift, then remove the 2 screws You may also
need to remove the 4 screws attaching the plastic console to the carpeted
section to ease removal. Once the console is out of the way, you need to remove
the kick board. There are just 2 10mm bolts holding this in, you need to lift
the bonnet to get at these there is one either side of the engine, right
against the bulkhead
Now that you have reasonable access to the bulb holders you
should be able to change the bulbs ok, BTW you can also get at the bulb for the
'fasten seatbelts' light from here. Good luck!!
Thanks. keep updated for any more query.you can rate this solution
