Digital dash portion lights out
2000 Celica GT
OK so I noticed that parts of my dashboard are out. On the right side of the dash cluster is the digital aspect.The entire right side (Digital)are out even the speedometer & Tach.
While the car is running I can take off the speedometer shroud & remove the gauge cluster.
Behind it are 2 plugs, the one on the right is for the digital. I can unplug it for a second or two & re-plug it in. Presto everything works.
However, when I start it up again everything's out :Speedometer, Tachometer, Dash lights, even the A/C, and the sunroof is confused. the A/C compressor is out, when the dash is out.
There also seems to be a power regulation issue the idle goes up & down which coincides w/the lights dimming (Pulsing) all which started when the dash went out.
I even replaced the alternator
Checked all fuses and relays. I was about to purchase an ECU
I also replaced the front light assy. Perhaps a short in the wiring has occurred there, over time.
Everything worked fine after the upgrade for 6+ months.
In-conjunction the drivers light low beam HID light has burned its electronic ballast. I replaced the bulb & ballast to no avail. I'm hoping all these complications are connected somehow.
Please help if you can.
