The ongoing global microchip shortage continues to affect automotive production, with General Motors opting to reduce the availability of some features for a range of different models. Now, GM Authority has learned that some Chevy models are being built without ventilated seat blower motors.
According to GM Authority sources, some units of the 2022 Chevy Blazer, 2022 Chevy Silverado 1500, 2022 Chevy Silverado HD, 2022 Chevy Suburban, 2022 Chevy Tahoe, and 2022 Chevy Traverse are being built without ventilated seat blower motors, as of April 4th production.
Prior to this latest constraint, affected units were already under constraint with regard to ventilated front seats. Now, however, not only are some units missing a control module due to the microchip shortage, but the blower motor as well.
Both of these components will be eligible for a retrofit at a later date. As usual, the window sticker for affected models will indicate which features are missing that would normally be equipped.
Check out the table below for a more complete list of Chevy vehicle feature availability with regard to constraints resulting from the microchip shortage. Note that in addition to constraints on the ventilated seats control module and ventilated seat blower motor, the shortage has also affected availability for the heated steering wheel feature, heated front seats, heated outboard rear seats, Rear Park Assist, and Front And Rear Park Assist.

The microchip shortage has dominated automotive production headlines all year, with models across GM’s U.S. brand lineup (Buick, Cadillac, Chevy, and GMC) affected. One recent report indicates that half of new-vehicle consumers would postpone a vehicle purchase as a result of the shortage. That said, demand for new vehicles continues to outstrip supply, with new-vehicle inventory days’ supply in the low 30s last month.
To combat the effects of future shortages, GM is now developing its own family of microcontrollers.
