A/C isn't working, no compressor engagement.

Hello guys!

2008 Roomster 1.9 TDI BSW, 245xxx km on the clock.

The A/C system is fully recharged !!!

At the beginning of the week suddenly A/C condenser fan stoped to spin when the a/c is turned on, compressor was working properly.

Somehow it fixed itself and in the following days everything just worked normally.

Started the a/c today and it blows hot air. The compressor isn't engaging and the fan isn't spinning.

Replaced the a/c compressor valve and still not working. The old compressor valve looks very clean, no debris at all. 

Checked the negative wire that goes to the valve and its ok.

Check the positive wire and it delivers only 10.2 volts to the valve. Is that normal?

My mechanic said it's and bad compressor but I still think it has some electrical issue.
