Air conditioning does not work in low mode

[Mautog]

Good afternoon, I have a Terrain and when I turn on the air conditioning in low mode it gives an over current warning, but when I turn on automatic or High it works normally, does anyone know what this could be?

Does anyone know where this circuit is located (circuit 12)?

Sorry, I can't answer that, but you might give a call to customer service at the A/C manufacturer. There should be phone or fax numbers in the manual you got with the owner's manual bundle. They might have an answer if you talk to a tech there.

I will try that, thanks.

Mine was doing something like that. It was hot in the coach so I turned the AC on auto, it went on high automatically. After it lowered a several degrees I tried to manually set it to low and it faulted with no code. I think it was seeing too much of a temperature difference from coach temp to set temp. Maybe try to get it within a few degrees of set temp or on set temp before switching to low. Sorry, but I haven't used the AC much.
