HelloCustomer what is the year of your truck and does it have manual or automatic climate control?
Your JA Expert,
2004 sierra ,automatic climate control,dual slide control and hers is the hot side not good.I need to know the location and a picture of the locations of the actuators. I am like other auto workers that lost there jobs and save money by doing it myself.
I feel for your situation, I know these times are tough. Here are your pictures. The procedure has you removing the dash, so see if you can cheat if you need to service these actuators.
