When I’m running my heater, the mode changes on its own (Defrost, to vent). They said it was a short, and a solenoid needs to be replaced. I can’t find any information for the mode actuator, or solenoid. Everything is about the blend actuator, which is different. I’m looking for part numbers and schematics, or better yet, video on how to fix this. They wanted $230 to fix it, but I’m handy enough. Thanks in advance!!

I bought another ride and it came with some HVAC issues . I’m not very good with wiring related trouble shooting so I need your help.
Its a 2002 suburban with the base hvac. No digital display and no dual climate.
*hot to cold switch doesn’t work
*vent change doesn’t work (blows out of front vents only)
[The Fan speed knob works fine And all fuses are good]
After reading up on the common actuator problems, I decided to try the relearn/calibration of the actuators. This literally did nothing and the part that has me stumped is that the actuators didn’t move at all during this calibration (you should hear them moving and calibrating)
So here is my thought on the problem. It’s either...
a) Both/ all actuators are bad and need replaced
b) The switch panel/ control unit is bad
c) There is something else and I’m lost.
Please help guys! Is there something I don’t know??
I have a 2003 Chevy avalanche the digital display quite working. I check all the wiring and fuses I do believe, and found no issues except now I can't get the mirror's electrical connect to seat all the way on the mirror's plug. It clicks but half of the connector is still up. Has anyone else had this issue, if so how did you resolve it? Thanks
