AC blowing Hot/Cold air through vents, car has Manual climate control

[dizzle1]

System had good pressure last time I checked.
Blend door actuator could be bad, I do get Drivers HOT/COLD Passengers air in every setting its most noticeable with the AC on, except when using heat.
AC Compressor could be leaking through seals I think “krivasauto” has a write up on it with a rebuild.

These are the only known culprits I can think of. Can anyone with manual climate controls relate to this issue or some serious answers to this issue which has plagued many W-body owners?

Check the heater blend door actuator through Heat & Air Conditioning, I read that it can be accessed by removing the drivers side kick panel.

My 2002 blows air hot/cold still when its off. Not much but its there. My 99 did that and when we replaced the blower motor/resistor it stopped. I have a blower motor resistor job in my future only 2 settings work for the blower high and highest 3 if you count the very low setting when its off.

All my buttons are working properly for the climate control unit, would it still be the blower motor resistor. I have to check the pressure didn’t check it since late fall and if its low ill do a AC Freon Refrigerant dye test.

yes check your pressure om ac there low i bet had 99 do the same way
