Cadillac XT4, CT4 And CT5 Ventilated Seat Blower Motor Retrofit Under Way1
GM has issued a service bulletin for a ventilated seat blower motor retrofit for certain examples of the 2022 and 2023 model-year Cadillac XT4, CT4 and CT5.

Affected components: ventilated seat blower motor.

It’s worth noting that select units of the Cadillac XT4, CT4 and CT5 currently have several other retrofits available. For the XT4, these retrofits include the heated front seats (RPO KA1) that are normally only available with the Cold Weather Package (RPO code Y19). In the meantime, the CT4 and CT5 models have their own retrofit for heated seats.
As a reminder, the Cadillac XT4 rides on the GM E2 platform, with production taking place at the GM Fairfax plant in Kansas City. Meanwhile, the two Caddy sedans utilize the GM Alpha 2 platform, while production for both vehicles takes place at the GM Lansing Grand River plant in Michigan.
