Hello all, I have a 1992 GMC k1500. I’m currently having trouble with my HVAC control module. When I try to select a mode or temperature, all the arrows start blinking simultaneously. This only started over the weekend. I’ve already changed the blend door actuators on the driver side and in the center. The one on the passenger side has been disconnected for as long as I’ve had the truck.
Could anyone point me in the direction of what to check next?
Attached is a photo for reference of what is happening.
Thanks in advance!
