Today I tried to charge my AC, I had to jump the compressor because there is no refrigerant and did not start.
I haven't been using the AC for many years now and it is time to get it to work again.
Once I started to charge, the gauge was set to 0 psi which was strange already...
I kept on going and after 10 minutes I noticed that one of the lines was white, see the picture below...
The funny thing is that it was until a certain point only (see the red arrow):
After half a can of 134a I gave up because the blue gauge was moving between 0 and 5 psi, so I am not sure what is going on.
I can only tell you that I had the dealer to test the circuit for leaks with pressure and they could not find anything.
I am not sure if perhaps my gauge kit is defective or else.
What do you think?
