Head Unit/AC/Camera Issues Tied Together?

[Casey]

Hello all,

I have a 2013 with 222k miles.  

I have several issues and i'm wondering if they could all be tied to one module?  

1st - The radio will not produce noise when we've had cold weather.  i have to cycle the battery, meaning i take the terminal off the battery to reset it.  happens so much i put a disconnect under the hood that i turn off and on to make it easy.

2nd - Rear camera is upside down most of the time.

3rd - Only the rear speakers work most of the time - so, the bluetooth phone connection seems like it doesn't work but it's just the front speakers not playing.

4th - AC blows cold on one side and hot on the other.  i know how to reset this though, it's just annoying.  

 

kinda another issue, probably not related, i have the oil pressure light show up a lot while idling.  red lights and such.  it seems to be worse in the summer so it scares me that it is an oil pressure issue.  i replaced the radiator fans b/c one wasn't working.  the problem went away for about a month, then came back.

 

can anyone help with the information provided?  

 

thanks a ton!!!!

As no one else answered, I'll take a stab at what I know. 

1. ACU not working when cold. Sounds like a defective unit (radio). I'd buy a replacement off Ebay and drop it in. Couple hundred.

2. Rear camera is probably the cause, but the audio control unit, the radio, has a video board in it to display the image from the camera. If replacing the radio fixes it, good. If not, new camera.

3. Replace the radio.

4. A/C blows cold on one enemy side means one of the actuators is defective. (Very common.) There are fixes by recycling the actuators but once they start to go bad, best to just replace.

5. Oil pressure light. Could just be a sensor problem. Are you running to oil described in your manual? Check the quality? Checked to make certain that there's no coolant in the oil?

 

(Turns the oil a milky color. You didn't say which engine your car has. 4-cyl eco are known to have bad heads between cyl 2 &3 which can blow the gasket and dump coolant into the oil, causing low oil pressure. It's critical to get this fixed asap if so. Destroys the engine if left unchecked.)

6. Replacing the fan. Possibly the fan  controller is bad. If you replace fan or controller, buy Motorcraft. Non-Motorcraft are known to be problematic.

 

If you used aftermarket, could be a bad fan. (Been reported widely by others.)

 

If you used Motorcraft, I'd suspect the control unit (located on fan scroud). Most people replace the fan assembly. (Fans, controller & metal shroud.) What I did. Only use Motorcraft. None of the others have a good record.
