First off I'll post a little backstory in case it trips any red flags.
2000 Grand Prix GT
My blower is only working on 5. Any other setting is the same as 'off'. I'm told this is a bad blower motor resistor. I'm fixing this in the future, it doesn't really bother me now.
Never had any issue with the A/C in the 6 years I've owned the car, never recharged it, never died on me.
Present poblem:
Occasinally I am hearing a squealing whule the A/C runs, hard left banking *seems* to cause it, it usually fades out in 10s or so. Aside from the noise causing me to wonder wtf is going on, I'm not bothered by it.
Yesterday, after running A/C for approx. 20 minutes, there was significant condensation leaking into the passenger compartment, dead center between where your legs go.
On top of this, I notice the driver side vents are not blowing nearly as cold as the passenger side. Driver side seems somewhat cool, but passenger side is nice and chilly.
My best guess(and where I hope you can provide some feedback):
In talking to a few people, they said they had similar issues(with one side blowing cooler than the other) and they fixed it by adding a can of refridgerant(spelling? Lol). The $7 cans, not the "one you use when its completely dead".
Other things suggested for the same issue with blowing cooler on one side is "the flapper is not closing completely". Vague understanding of this.
As far as the condensation coming in, all I have heard is that "[possibly] my heater core is shot".
Thoughts? Similar issues? Any feedback is appreciated, and please keep in mind I have varying levels of understanding of different engine components, so I would appreciate a dumbed down explanation if its not too much trouble. Thanks for reading this.
