Hi there!
I got a few grelims on the climate controls on the 02 Yukon, nothing outrageous. I don't know how these work yet, do they run off vacuum or if they electrically actuated... (well I think I have figured out that part... sounds like electric) ?
Issues:
1) Few weeks ago when I plugged in my scanner the only code on the vehicle left was a B3761 Code – Air Flow Control 3 Feedback Circuit Short to Ground or Open.. I figured that was from battery drain and restart but maybe that points to something.
2) AC button needs a heavy press and takes many attempts to light on/off, but the ac works well when ON
3) Heat doesn't work unless it's turned all the way to the right past the red mark in Full Heat mode
4) Only blows through the dash vents. Doesn’t blow out of the floor or defrost. I can't quite tell if it's the actuator or the controls (Any tips on telling which may be faulty? Any tests on Tech2?). Actuator part number on driver side 52473356, passenger side 52474810.
While I am able to deal with these problems as things are still sort of functional, figured I would at least start a thread to 1) document what problems I'm having, record codes, pictures 2) see if this issue is common and get an idea of what it would take to fix.
My climate control module part number is 15126604 and sure could use a new one... I am usually into buying OE parts only. But good luck finding one. Any reasonably good quality replacements you have had good luck with ?
