Does anyone know if somebody makes a replacement/retrofit blend door for the boxes? Specifically, 1989 manual hvac. Or am I stuck making my own?
I have a job to do that I don't want to do, but what are you gonna do, except just do it? =-\
Some of you may recall the odd heat behaviour I have had in the box for the last couple winters (no real heat until the car has been driven for about a half hour, when all of a sudden you hear the air pattern change and you get blasted with heat-the way it should be). I checked the controls, etc, moved the blend door arm by finger (with cable disconnected. And yeah, also checked that the cable moved the crank arm properly) to feel & hear what sounded like the blend door moving from one position to the other... Well, the past couple weeks my AC has been less than cold, but no constant clicking of the compressor that would indicate a low charge, so anyway, yesterday, I turn on the ac and shiver me timbers, ac as I remember it. ICE cold. So I pondered for all of a fraction of a second and the blend door is the only commonality for heat and a/c. So checking/fixing/replacing the blend door is my job when I get the will to pull the plenum. Arm moves as it should, hot/cold blend when actually trying the stupid thing does change, but in actual use temperature is never as hot or cold as it should be.
