AZC system calibration problem?
|Model:||Grand Cherokee Limited|
Recently replaced blend doors bec. no heat on either side. Used a kit from online somewhere. Fix worked for a few days, then like clockwork, every 3rd ignition start, passenger side will only blow cold. Shut it off for a few mins. and I can hear the doors calibrating and next start it will work fine until start #3. Repeats over and over.
I have recalibrated the AZC multiple times manually by pulling fuse in engine compartment and it hasn't helped. HVAC system not throwing any error codes either.
