Tell him to search "Rear AC" on Techconnect...he'll find it. Info became available 7-25. It involves some simple tests to actuate this and that, then the part number to replace the Front control head. Not a TSB.

 

Thanks TN Tech!

I thought my rear A/C unit was whacky until I re-read the manual and made sure I had the "Rear" button engaged and rear temp displayed on the front unit. Once I did that, everything seems to work OK.
