Condensers rot through on radiator side get your air con guy to put some die in it and use his black light to find leak ,I fitted a new one I got from EAI and he gassed it ,no probs
If you need to replace the condenser, remove the front bumper, disconnect the hoses and pullout, new one in the same way, did my daughters not so long ago, had me scratching my head until realised the bumper needed to come off.,
