My A/C went out suddenly


Hi listers.

My A/C went out suddenly. It was charged and worded fine. No compressor whinning or any bad issue before.
I stopped for 2 hours and when I came back no A/C, when I push the button the clutch doesnt engaged.
Checked :
- the a/c fuse is OK.
- the a/c relay OK (I swap it with the honk one).
But :
- I short the a/c relay with a jump wire : the A/C clutch engaged but a weird smell appeared after 15 sec. :-/.
Midas checked the charge there was ony 700g instead 1300g of R-134a. Even full charged nothing has changed.

Any advice is welcome.

The first thing to do is locate the leak. The system has switch that won't allow the compressor to run if the refrigerant level is too low. Leaky condensers are notorious on those vehicles. What we see is that a crack develops at the lower passenger side mounting bracket.

Take care,
