Door Open Buzzer

Can anyone help. My recently aquired '95 Ultima cossie has a fault in that the door ajar buzzer sounds continually if the drivers door is open, regardless of which position the gear selector is in even with no key in the ignition, in addition there is no "light on" chime presumably because the buzzer is sounding. Everything else seems to be working normally. 
Anyone had this happen before?

Have a look at the relevant link in Fault Finder. Door switch. Here.
Links are listed in Transmission concerns.

Does the transmission switch signal the EECV because the car will start OK in P or N but not in any of the drive positions which suggests to me that the transmission position selector switch is probably working normally.

Right found it, page 10
PDF: Starting Systems
'A' comes from starter inhibit relay, goes through separate switches in the 'PRNGL switch' (as I thought, from memory), so nothing to do with the PRNGL range sensor for PCM.
Thence it goes to PATS, so PATS can disable starting. If no PATS, goes to ground (chassis earth). Either way PRNGL enables starter inhibit relay by grounding it in 'P' & 'N' only, using different contacts to the gearbox ratio selector (range sensor).

Thanks for that Mike H, but still confused.
If PRNGL is selecting the right gear then it must be positioned correctly and transmission range sensor is sending correct signal to the PCM.
PATS must also be getting correct signal to allow starting , or have I got that wrong ?
Where does the buzzer module get its signal from- is it the EECV?

This is getting more complicated - it could be Powertrain Control Module on page 10, getting high Volts when when it should be low in 'P' position. Most likely a bad wire connection? I presume starter work in 'P' & 'N'? If so possibly bad wire between P102 & A147
There's also a separate reverse switch in the PRNGL, see here:
Park Position System
Doesn't show how that connects to the PCM but it must do somewhere.

Mike I must be missing something -can't find P102 or A147 on the 24v arm of the tree on Page 10.
Yes it does start in "P" and "N"
I see the separate reverse switch within the PRNGL switch-is there a separate switch for "P" and "N" which links with the door switch?
Interesting that on my other 24v as soon as you press the release button on the selector lever the buzzer sounds (with door open) even before you move the lever-even a little!
More and more complicated.
Simmo ,would it still be the door switch as the noise stops if you close the door or just press the switch in

The release button on my 2.3 functions the same as on your other 24v so I would imagine that may be your problem.

Thanks Tompion, thats helpful but I wonder what the button moves to do that. Must be mechanical via the push-rod because apparently only 2 wires go up the stick ,-to the O/D button.

Is there not a little mechanical switch at the bottom of the gear lever ? I always cut the wire at the timer module on the funeral vehicles because the noise is unnecessary and we tended to always use the handbrake.

Thanks gozz. Do you mean a switch at the bottom of the gear selector release button push rod ? I am assuming the push rod is for the release button but I cant find a diagram which shows where it goes or just how it works.Which wire did you cut?

Yes Glyn,I vaguely remember a little switch somewhere inside the centre console,if you remove the plug from the timer module near your left knee inside the trim board and hold it with the contacts towards you and the locating lug at the bottom,the wire is the extreme right one on the upper row,usually orange and yellow,but I had one once that for some reason was orange and green.

Maybe that just jiggles the stick slightly so the contacts are disturbed; so sounds like they may be wearing out.
