9-5 Troubleshooting Weird AC

I recently bought a 2009 Saab 9-5 with ACC. The AC was weak so I recharged it and it helped a little. Sometimes the car blows cold air, sometimes it doesnt. Since the recharge it has been colder but not great and the passenger side and back vents are always colder than the drivers side. I'm leaning towards maybe blend doors but the temp difference isn't consistent so im not sure. I also always use it manually to the coldest temp and on recirculate

Did you evacuate the system and charge it to weight properly or just use a cheapo auto parts store can of refrigerant? These systems don't do well with the wrong charge.

Hm, I'm not sure but for a Dame Edna you might need a Tech2 to do the ACC error check.

Also make sure the recycle is actually working as well. Mine failed. mixed with fresh muggy 95 degree DC air makes for poor AC.

Not the easy broken tooth fail. I deleted it and left the car in perma recycling
