We have a 2011 Laredo 303TG. I have noticed that our A/C doesnt't want to work on the low fan setting, only high. This has been going on for about a year now. We were out 4th of July week and it started to work on low again, however then noticed a crazy loud (for lack of a better description) thumping/banging noise. At first is sounded like someone was pumping out or tank, until I realized it was coming from the A/C Unit. Turned it off for a bit and now it's back to only working on high fan setting. Not sure i anyone else has had this issue before.
