2005 GMC Sierra 2500HD, left side low and high beams out, new bulbs, fuses good. No power at the sockets. Could this be the high/low switch on the column?


It shouldn't be the high/low beam switch, as that switches the high/low beam relays. One high beam relay supplies power for both sides, one for low beam, both sides. If you were to lose switch function or a relay, you would lose the high beams or the low beams, but not for just one side. It would be interesting to probe the fuses with a test light and see if you're getting power to and through them. If you are, the problem would be between the fuse box and the headlight, if your not getting power to the left head light fuses, the problem will be in the fuse box. Good luck!

Why is it displaying sc300 error?


High voltage power output error The measured voltage is not correct when the EGB measures each charge output (charge, development, image transfer belt unit, and transfer unit).
  • Disconnected or defective high voltage harness
  • Defective high voltage power supply
  • Defective EGB
  1. Check or replace the harnesses.
  2. Replace the high voltage power supply board
  3. Replace the EGB.

1994 jucuzzi high speed jets dont work ?


Hi,
If the motor is not going to high speed then you have one of two things happening...
The relay for the high speed is not working right or the high speed is burnt out on the motor...
Check the high speed connections in the motor for power... if you have power it is the motor... if no power there then the control is bad...

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.
