How to remove Instrument Cluster from a 2005 Lincoln Aviator

One of the contacts for the turn signal bulbs inside the instrument clusters is loose and may need resoldering. You will need to open up the cluster and check for continuity from the turn signal LED bulbs to the electrical connector plug. In our case, we found an open circuit.
Follow this procedure to troubleshoot this problem.

1. Remove instrument cluster from the dashboard.
2. Open the instrument cluster. Remove the back cover from the instrument cluster.
3. Once the circuit board is exposed inspect the contact where the turn signal sockets are connected to the circuit board. In our case one of the turn signal socket pins was broken and not making contact with the circuit.

digital part of dash ???? Instrument cluster , gauges etc.... Have the instrument cluster checked for DTC'S - diagnostic trouble code's , yes the instrument cluster an the BCM - body control module (GEM)
Is this what your instrument cluster looks like ?

Principles of Operation
The instrument cluster is a hybrid electronic instrument cluster (HEC). The instrument cluster gauges, warning indicators, and message center displays are either controlled and driven directly through hardwired circuitry, or the information is requested and received through the standard corporate protocol (SCP). The instrument cluster has self-test diagnostics capabilities using the diagnostic tool.

      1. NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 mi) or more to relearn the strategy.
         To install, reverse the removal procedure.

There are 4 screws that hold the instrument cluster in .and before you disconnect the instrument cluster you have to up load information to scan tool for down loading to new instrument cluster.

Which light is out? Is it an instrument cluster light, or one on the temperature or A/C cluster? It it's an instrument cluster light, here is the process: (I'm assuming the 99 is similar to the 98) Remove the bottom dash panel under the steering wheel, remove the instrument cluster cover around the steering column. This will reveal the screws that hold your instrument cluster cover in place. Remove this cover and you can then see and remove the 4 screws holding your instrument cluster in place. Pull your instrument cluster out, remove the main wire connector, then you have access to all the instrument cluster lights on the back side. Hopefully you remember which one is out!

1. Disconnect the negative battery cable.
2. Remove the instrument cluster.
3. Remove the retaining screws for the instrument cluster lens and cover assembly. Remove the cover and lens.
4. Remove the retaining screws for the gauge or warning lamp to be replaced and remove the gauge or warning lamp. To install:
   
5. Place the gauge or warning lamp into place and tighten the retaining screws.
6. Install the instrument cluster lens and cover assembly.
7. Install the instrument cluster.
8. Connect the negative battery cable.

Removal & Installation

1. Disconnect the negative battery cable from the battery.
   
2. Remove the lower steering column cover-to-instrument panel screws and the cover.
   
3. Remove the instrument cluster trim plate-to-instrument cluster screws and the panel, then allow the panel to hang to the left side by the wiring.
   
4. Disconnect the electrical connector from the rear of the headlight switch.
   
5. Disengage and remove the headlight switch from the instrument cluster trim plate.
   

To install:

1. Connect the electrical connector to the rear of the headlight switch.
   
2. Engage and install the headlight switch in the instrument cluster trim plate.
   
3. Install the instrument cluster trim plate-to-instrument cluster screws and the panel.
   
4. Install the lower steering column cover-to-instrument panel screws and the cover.
   
5. Connect the negative battery cable to the battery and check operation.
   

remove the cluster(should be able to insert Small flat head screwdrivers into slots on plastic trim of cluster. Lower your steering wheel down and remove key. wait approx 30 seconds until cluster is off( means that the interior c.a.n. has went to sleep) unplug cluster and see if the bulbs you wish to replace are accessible from the rear cover. if not remove retaining screws and un clip rear cover from housing. You should have access to the back lighting bulbs
