I checked to see if I had any codes today and this came up P0514 Batery Temp. The truck had been doing good with new engine. So just wondering what this code ment. The only problem i have noticed well wife noticed are the vents on her side dont blow as cold as driver side and sunday they would blow warm at times.

 

It's common on '04 up and is a code that comes and goes often depending on the air temp outside. Reset it and carry on.

 

Different temps coming out the vents is either a fin temp sensor location or your A/C system is low on refrigerant. Probably low on refrig. Sometimes can happen when replacing engine. Moving compressor out of the way may cause a small leak. Take it back and have the A/C checked.
