I have the Denso touch screen system on the final MK3 face lift model
I have also scanned for DTS codes and returned none.
However, since the problem you have only affect the A/C compressor, and having checked 4 volts on the compressor (should be 12V) i will include the wiring diagram getting to the compressor, so you can check the related wiring, clean or even replace as needed. click here for details
Kindly get back to me with your findings, or if further assistance is needed.
Thanks, ***** ***** not explain why I would get AC when the outside temp drops below a certain temp (i.e. Early mornings).
Hi, I have now check over the wiring. I cannot find any faults relating to the wiring.. I've tried shorting the low pressure sensor to see if the compressor clicks, and it doesn't.
I can 12v to the fan, if I connect this direct to battery it works. What I'm not getting now is any volts to the compressor.
I've now managed to test the compressor by connecting it to the battery. The compressor clutch engages as expected. The fan doesn't start, I didn't notice any colder air coming into the cabin tho
The inside blower was on, I meant the condensing fan had started. I don't have the tools to test the pressure. When I was with the A/C engineer he was reading pressure on both high and low pressure valves.
With the compressor wired to the battery the clutch remained engaged for the entire time. When it's connected back to the car, the clutch doesn't even try to engage, you can see the clutch does nothing.
