Ok i spent the better part of the day searching online and im not an AC expert so ive narrowed it down to the evaporator if im not mistaking...

My question is what is that clicking sound behind the dash on the passenger side when the AC is on?


my Ac blows cold air but not as cold as other cars so im going to have it serviced soon.. i filled it up with the recharge kit from autozone but it didn't help much ill have to have the entire system inspected for leaks etc.. i found a really nice DIY to do charge and check the system which requires some tools like vacuum pump so i might just do it myself but id like to get some tips if possible on how to make it cooler.
