3685 FL w/2nd A/C

[Bill DeMeulle]

I have added a 2nd A/C to my 2003 3280, however it is in the bedroom. One thing you might check is the pre-wiring,I found out the pre-wiring only allows the A/C to run when the main A/C is not running,I paid to have it re-wired to allow both to run at the same time. They now work perfectly when we are in the desert.
