Reprogram AC/heater door mode

so my guess is want Ac COLD ARE
OR JUST THE MODE ACTUATORS FAILING
there is A manual AC system and Climate controls sys.
the are not the same.
I guess AC wanted,
the blend door stuck open is wrong,
if stuck open thee will be no cold.
the blend door closed and blocks the heater core 100%
if max AC cold is selected.
and recirc mode too is needed
a tiger by the tail, this VACUUM controls monster.
we only can fix them in a shop with a vacuum hand pump with vac gauge, and the service manual to ID hose colors
guessing is not easy here
there are 2 blend doors, left and right to fail.
blend is electric so this 2001 system is hybrid of elect + vac controls
air inlet it vacuum servo.
left and right mode actuator is electric motor drive.
frost defrost is VACUUM servo drive./
the service manual has vacuum logic table matric
showing all vacuum status, V or NV for each mode
and manual system is not like CliaMATE CONTROL

manual controls, I can not publish the whole HVAC chapter here.

17= heater core
6,= evapcore (cold)
11 is blower
16 is vac controls. dash
13 is engine vacuum, intake man, 20"hg at idle.

Check the radiator to make sure that the coolant level in the radiator itself is not lower than the level of the heater pipes.
Look to see if their is any heat going through the heater pipes. The radiator or the the heating system could be having problems and it should be looked at by a mechanic.

Check your mechanics manual. There is most likely a sequence of times you must turn your vehicle on, then turn the key back one click. you can actually hear the module trying to reprogram itself. If a vandal was at fault and damaged anything, you may have to take it to a mechanic. My daughters Chevy Venture was stolen and destroyed. Little by little we put things back in order..glass/modules/ignition etc. I was not able to reset the system, and had to take it to a dealer. Still cheaper than a replacement van though. Good Luck! :)

The clicking you hear is the vehicle asking for the program sequence to reprogram the locking system. Apparently something threw it out of sequence, ( a battery change , jumpstart, voltage spike , etc). The programming sequence that mazda uses is really kinda crazy. I was able to locate the sequence to try. If it does not work have the dealership flash the pcm, (another word for reprogram the powertrain control module). Here is the sequence:
1) Get in MPV with ignition key, and all fobs for the vehicle.
2) Close all doors and remove ignition key if it is in ignition.
3) Open driver's door
Note: Steps 4 and 5 must be completed in under thirty seconds.
4) Repeat the following three times
a) Insert ignition key
b)Turn ignition switch to on and then to lock
c) Remove ignition key
5) Repeat the following three times
a) Close driver's door
b) Open driver's door
Locks should all lock and then unlock within a couple of seconds--you'll hear the clicking sound
6) Press any button two times within five seconds on fob being programmed.
Locks should again lock and unlock
7) Repeat step 6 for all other fobs being programmed. When done with last fob, wait a few seconds and then you should be done with the reprogramming. Each fob should now work for this vehicle.

Sounds like you have a problem with door or diverter in the a/c/heater duct under the dash. That door is not opening or closing, whatever the case may be.

If you also replaced the control board inside the fob you will need to reprogram the fob and any others you have for the truck as well.

MAKE SURE BLOWER MOTOR OPERATING IF NOT CHECK FUSE AND RELAY.ALSO CHECK HVAC FUSE THIS CONTROL HEATER + AC CONTROL SWITCH AND MODE SELECTION FOR OPENING AND CLOSING HEATER DOOR OR HEATER CONTROL VALVE AND AC+ DEFROST AIR DOOR.IF BLOWER AND HVAC FUSE OKAY.IF YOU HAVE MANUAL HEAT CONTROL MAKE SURE MODE SWITCH IS RECEIVING VACUUM. YOU HAVE TO REMOVE HEATER CONTROL SWITCH AND CHECK TO SEE IF GETTING VACUUM GETTING TO SWITCH LOOK FOR BROKE DISCONNECTED VACUUM LINES IN THE DASH AREA.IF YOU HAVE CLIMATE CONTROL.YOU COULD HAVE A FAULTY ELECTRICAL HEAT DOOR ACTUATOR.SOME CLIMATE CONTROL CARS HAS THE CLIMATE CONTROL PROGRAMMER HAS TO BE REPROGRAM BEFORE THE HEATER AND AC WILL WORK AGAIN.YOU NEED A DEALERSHIP SCANNER TO CHECK IT OUT.BUT IF YOU HAVE MANUAL CONTROL CHECK TO SEE IF YOU GETTING VACUUM.IF YOU GETTING VACUUM AT HEATER DOOR VACUUM ACTUATOR OR HEATER CONTROL VALVE EITHER ONE OF THOSE COMPONENTS COULD BE FAULTY.WARNING YOUR VECHICLE HAS AIRBAGS YOU HAVE TO DISARM THEM BY REMOVING FUSES WAIT 20 MINUTES BEFORE WORKING ON DASH AREA.YOU HAVE TO CRANK CAR UP TO CHECK TO SEE IF YOUR HVAC GETTING VACUUM.

Owen, Try this Get in close doors, don't lock them. Put key in, cycle the key on & off 4 times. Ending in the off position. After the 4th time & within 10 seconds, press the lock switch on the drivers door. If you here a chime, they are reprogramed

check the connections for the front heater blower and also check the relays and fuses

it sounds like you have a blend door problem. the modes for the heater/ac system are moved by little motors . you use a scanner to acuate them individuly on some of them the dash has to be removed to access them. hope this helps
