Thank you for asking your question today. Ok,good. That is very likely, since the battery was replaced. Check the fuse first, if not then you will need to go to the dealer. Below are the the DEPOWER and REPOWER Procedures.

Climate Controlled Seat System Description
NOTE: When installing a new climate control seat module (CCSM), it is necessary to carry out programmable module installation (PMI).
NOTE: Faults that cause the climate controlled seat to shut OFF after more than 40 seconds are usually mechanical in nature, such as incorrect foam installation, duct blockages or misaligned TED.
The climate controlled seat system is able to heat and cool the front seats. Each climate controlled front seat is controlled by a switch located on the center console.
Both the driver and front passenger seat has an independent climate controlled seat system installed. A climate controlled seat module mounted to the bottom of the seat cushion electronically controls the climate controlled seat system. The climate controlled seat system receives power from both the battery power and vehicle run circuits. The vehicle must have ignition ON, engine running and the switch set to HEAT or COOL 1, 2, 3, 4 or 5, for the climate controlled seat system to activate. The switch will illuminate to indicate the desired operating mode.
Cabin air is drawn through the seat fan motor and distributed to each of the thermo-electric device (TED) modules located in the seat cushion and backrest. The TEDs then heat or cool the air. The air is then directed into the foam pad B-surface. Channels in the A-surface of the foam pad are used to distribute the air along the surface of the seat. Once the system is activated, the climate controlled seat module uses a set of flexible algorithms to control the heating/cooling modes, and the fan motor speed based on the climate controlled seat switch settings.
The TED uses a ''Peltier'' circuit of P-type and N-type semiconductors connected in series using copper electrical conductors. The semiconductors are sandwiched between two insulating ceramic plates. When current is applied to the TED, one side releases energy as heat, while the opposite side absorbs energy and gets cold. By reversing the current flow, the hot and cold sides reverse.
The temperature differences between the individual HEAT and COOL settings is minimal. For example, it is difficult to distinguish between LOW COOL and MEDIUM COOL settings. Monitoring the seat temperature at different HEAT or COOL settings should not be done as it is ineffective in confirming climate controlled seat system operation.
NOTE: The presence of overtemp faults (DTCs B2729 and B2730) can be induced by incorrect operation of the climate controlled seat system after an initial HEAT setting has been attained. If a HEAT setting is repeatedly turned OFF and ON in an attempt to increase the seat temperature, an overtemp condition can result and the DTC(s) will be set.
