Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi. The most common cause of your concern is the mode door actuator. It is located on the left hand side of the heater box to the right of the drivers feet. You can inspect to see if it is moving when you are changing the modes on the hvac module. Let me know if that is something you can do. Thanks.
Yes that is correct. The panel does have to be removed. There is not enough room to access it.
I cant say it wont because removing the battery cables fixes many things these days with all the computers. It would be worth a try.
