My cluster was on its way out when I bought the car about a year ago, I replaced the power supply caps in the cluster and it fixed it till last night. Last night it was good and cold, I turned the key on let it glow, all the lights came on, the clock and odometer worked but none of the needles were moving and there was a high pitch noise coming from the cluster. The car started right up as usual but the cluster didnt come alive with it, after running for a bit the tach went clear past 5K rpm and stayed there. I went ahead and drove home and parked it in the garage hoping the the heat would bring it back from the dead, the tach started working again but the rest of them were still dead. The battery is brand new so I check all the grounds but did no good so I took the cluster out and desoldered the power supply cap and checked it, it checked out just fine so no luck there. I had been having problems even once in a while the gauges would not be accurate, after cycling the key off and on they would go back to the proper positions. So it looks like the 10417A stepper motor driver/voltage regulator chip has gone bad. I have a 4 cylinder gasser B4 cluster on the way to use for parts, I will finish up this post when I get it and finish up fixing my cluster.
Here is the tdi cluster after taking everything off the board
In order to remove the white plastic housing from the circuit board all the LED's and both LCD's must be unsoldered and removed (be extremely careful with the LCD's the glass is very easy to break)
This is the circuit board after everything is removed
Location of the 10417A after removal
The cause of all the problems the Elmos 10417A
Tools needed for the job
desoldering pumps, forceps, tweezers, screw driver
Soldering station
Hot air rework station (the key to removing the chip without damage)
My workbench
More to come when i get the parts cluster, I will do disassembly in more detail and reassembly
