You have a leak somewhere in the system if you keep having to put freon in. The only solution if that's the case is find and repair the leak.

I had the same problem! The Antifreeze leaking is very possible that it came from the intake valve. What they (Good mechanic) did to mine was put what they refer to as "Tablets" in the Antifreeze coolant. This is an anti-leak temp fix. Since then I have not had any problems with it. This had been done about 30K miles ago and I now have 139K on the car.
 
If you brought this to any trustable garage and they "Cleaned out the sludge" then they didn't know what they were doing. If there is slug in the Engine more often then not, if cleaned out will pose more problems then if left in. This is what my Mechanic told me and I did some research and found out to be mostly true. There are times where they can clean this out but they have to also do other replacements of certain parts as well. Hope this helps!

Certain AC Settings not working. by jables1

Hey all, brand new here and I'm pretty desperate for answers. I have a 2000 Pontiac Grand AM SE and my AC is acting up on me. About 3-4 months ago, the AC stopped working all together on settings of 2 or lower. It's slowly gotten worse as it now only works on a setting of 5. Just curious if anyone knows what might be the cause and how much it might be to fix it.
 
Thanks!

Most likely the blower motor resistor is going bad. Search in this forum and the Olds Alero forum for it, it's been discussed many times in the past.

Little heat coming from heater by skaye

I have a 2000 Pontiac Grand Am (V6). I'm not getting much heat from the blower. The temp. gauge shows just above 40 degrees Celcius. Could this be a thermostat problem?

Could you please point me in the right direction? Not sure where blower motor resistor is located in my 1999 Grand Am. Lost 1 and 2 speed controls a couple years ago and now I have lost 3, 4 and 5. Hoping this is the problem and any help you could offer would be greatly appreciated!!!

It's in the passenger side footwell on the bottom of the plenum. You will have to remove the trim panel under the dash. Some folks remove the glovebox for access but you don't really have to unless you think you need to. Look for the connector on the bottom of the plenum, it's way up against the firewall. Remove the connector. There's two screws that hold the resistor board on to the plenum, the front one isn't too bad to get to but the back one is tough since it's up against the firewall.
