Instructions for removal and
cleaning of MID (multi information display center)(the in dash unit
containg the speedometer and tachometer) to restore pixels.

1.Remove 2 screws above tach/speedo with a T10 torx driver.

2.Pry out upper lip of housing with a flat blade screwdriver.

3.Disconnect 3 wire harnesses in the back of the housing and slide
assembly toward passenger side of vehicle. (Make sure steering wheel is
down and telescoped fully)

4.Place assembly face down on some type of soft towel and find and
remove the wire harness going from the speedo/tach assembly to the
module attached to the back. (Black plug at the top of assembly).

5.Push button on the bottom of assembly and slide the module sideways to free it from the front assembly.

6.Locate the five “X” type connectors holding the front onto the main
housing. Twist these connectors slightly so they line up with the holes
on the housing.

7.Press the four clips (2 on top/2 on bottom) and slide the assembly
out through the back of the assembly holding the front clear covering
(that covers the faces of the gauges).

8.Now lay the tach/speedo assembly face up on the towel and remove all
of the torx screws on the face (about 8-10), this will NOT allow you to
open the housing, but it will loosen it enough so you can get a spray
nozzle into the circuit board under the cover.

9.Spray any and all connections you with the contact cleaner
(non-residue/quick drying/plastic safe). Quickly dry the connections
with compressed air (be sure to hold can upright to prevent liquid from
being expelled)

10.Spray all holes and connectors and the connectors that plug back
into the dash board. I also sprayed the actual connectors in the dash
as well.

11.Reassemble the entire unit and make sure it is DRY before reinstalling in the vehicle.

This is what worked for me, it restored all of the pixels to 100% brightness.

Good Luck to all, BE CAREFUL!!!!
