The AC is often used to cool batteries and the motor so if that's packed in then it won't help. You'd think the car would monitor this and report back a warning if the AC was becoming less effective or if there was pressure loss in the system.I dont know if this is in any way related but on Friday I was feeling smug in the knowledge that my car was preconditioning before I left work. Got into a fan oven! The vents were blasting hot air at me on the hottest day of the year.
Either way, it is getting dumped at the dealer on Monday morning so we'll see what they say.
