I heard some cracky sound in my Steering wheel. Even when the road is smooth, I still here that sound randomly.

Steering Wheel Noise

When you hear a new noise in your car it is a good idea to turn down the radio and continue driving normally to try and determine where the noise is coming from, when it occurs, and how to describe it to your mechanic.  Since the steering system in your car is connected to so many things, steering wheel noise can come from lots of different places.  To allow your front wheels to carry the weight of your car, turn, travel with your suspension and deliver power to the ground, there are lots of links and joints that can make noise.


If you hear crunching from just behind your steering wheel you probably have a bad clock spring.  The clock spring in your car is an electrical connection that maintains contact even if one side is rotated.  It consists of a round contact pad on the steering column and a small spring on your steering wheel that makes contact.  If that spring is broken or damage it will crunch as it travels in a circle and should be replaced.

Hyundai Sante FeI have a 2006 Hyundai Santa Fe V6 recently bought. I was told the driver side window master switch needed to be replaced. So I bought a certified used one. Put it in and the windows are still not working. None of the windows will work in fact please help????

Power Window Won’t Work

First thing to do would be to confirm power is getting to the master switch you just installed. The old one may not have been bad either. Battery positive gets tot he power window master switch through a fuseible link and a power window relay. Use the provided power window wiring diagram below for reference.

Intermittent start in Park. Sometimes need o shift to Drive, then back to Park, then try to start. EBS and ESC lights come on for aperiod of time and then off again.

My guess would be that the starter is causing the issue. Intermittent issues are difficult to diagnose but not impossible. The diagnosis and testing can only be performed when the issue is present. So when it won’t start.

Battery light is on. Checked alternator, battery and wires. They are working properly. Not sure what to check next

Check the Belt and tensioner assembly. The battery light comes on when the battery is not being charged. This can be from the alternator not working. Bad connections to the battery or alternator.  A bad cell in the battery. If you are seeing that the alternator is charging, my guess would be the battery is faulty or you have a blown fuse.

2012 Hyundai Sonata Hybrid

I have code p1777, PCM out put malfunction.
Where I can start to check? What that code means?
thank you

Code P1777 – OPU Power Control Circuit Failure

Code P1777 is set and sent to the PCM/TCM when OPU detect error into OPU internal power control circuit.

Possible Causes:

  1. OPU Power stack error
  2. EOP stuck error
  3. 3-phase wiring short to VB,GND

OPU Power Control Unit Location

OPU Power Control Unit Location

Code P1777 General Description

The HEV uses the hydraulic pressure that in addition to mechanical main hydraulic pump EOP (Electric oil pump) controlled by OPU (oil pump unit) to take command by PCM/TCM generates oil pressure to operate clutch and U/D brake.

When low speed driving or engine auto stop regardless of driving mode (EV mode or HEV), when hydraulic pressure becomes low because of mechanical main hydraulic pump rotation in low speed or stop, OPU supplies hydraulic pressure on U?D brake by operating EOP in order to protect Friction Element.

When shifting the driving mode from EV mode to HIV mode, EOP supplies hydraulic pressure to the engine clutch in order to use engine power when the driving mode shift is completed (Engine clutch: wet type multiple disk clutch that connect or disconnect the engine power between engine input shaft and transaxle input shaft)

What to check

According to the Manual you are to inspect the terminal and connectors first. Then check the component itself.

  • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
  • In order to check the component, the manual advises to clear the code(with a scantool) after cycling the IG on and off two or three times. If the same code returns, substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM.

2009 Hyundai i20

Hi – I am desperately searching for the Wiring diagram for a 2009 Hyundai i20 1.2 Classic vehicle. I need the diagrams for the Engine Bay as I had a loom fire and need to replace the cables that have been burnt.

Hyundai i20 wiring diagram

At this time we only have access to US Domestic and import model diagrams. I see you have requested this information from several places over the internet. Unfortunately no one seems to have this diagram available in free form.

This may be an instance where you will need to contact the service manager at your local dealership and request the information from them. Some may even be able to present you with the wiring diagrams for free. You never know unless you ask.
