Ford mond - Head unit turning off by its self - Mrken55
After I had a new Aircon compressor fitted, my
Head unit (Ford original) started turning its self
off by its self, which kills the Aircon, I also get the
Square box on the radio display telling me it will
turn off in 60 minutes While the engine is running,
only use to get this when the radio was turned on
when parked and engine not running.
After about half hour to an hour I can turn it back
on.

I guess this is a mk 3 model with the integrated navigation and climate control display.? Not too sure how a new compressor can affect the radio operation

It’s a mk 4 with integrated navigation audio and climate controls
As it only happened after the compressor was fitted,
And the Aircon controls are on the head unit,
Surely the controls would have to be linked to the
Aircon compressor via cabling from the head unit
As you control the Aircon from it.
And as I said it started with the Aircon turning its self
Off.
I thought a cable could be lose after the new compressor
Was fitted.

Something strange going on here. There is no direct connection between the climate/nav panel and the a/c compressor. The circuit runs through various electronic modules,relays and fuses to make the system operational. What happens if the a/c pump is disconnected?
