Instrumental Cluster Issue

[evilevo]

Hi guys,

Recently bought car for my dad its a Toyota Corolla 2001 XL AUTO. While driving the car at night we noticed that the cluster doesn't show what gear position I am in i.e. PRND2L.
I have checked all the fuse under the driver side kick panel and also checked the fuse under the bonnet but I cant find any blown fuse. Cluster works fine apart from not indication what gear position I am I.

Have tried to take the cluster out but couldn't, instead took the face plate (plastic bit) off the cluster to see if there is a bulb that could be blown but I couldn't see any bulb near the gear position indicator.

Also I noticed that the shifter light wasn't working when head light is on, so when I pulled all the panels i.e. the center console and all the surrounding around the air unit to replace the bulb when I noticed that there was a plug (round female plug) sitting close the shifter but I couldn't find any place to put that in. Could this be the cause of the problem?

What I am trying to understand is what send the signal to cluster to indicate I am in D or R or P? Does anyone here have a a wiring diagram for Corolla 2001? Have tried to look for manual for 2001 Corolla XL but no luck. Can someone here help please?

Thanks guys

Assuming by 2001 Corolla XL you mean NZ New AE11X. This means that there should be individual light bulbs under the PRNDL.
Have you checked all positions to make sure that the most common positions (PRND) are not simply blown? There should be 4 screws holding the instrument panel (no need to remove clear plastic), once you have them off you should be unclip plugs underneath (two or there).

As far as I know the gear lever position signal does not come from gear lever, but instead it comes from multi-pin plug on the gearbox.
If that switch would be disconnected you would not be able to start the car (among other issues, as it signals ECU which gear position you have selected).

There is a single light bulb that lights up all PRNDL positions on gear lever itself (separate circuit from dash, it is hooked to same circuit as park lights).
