Hi Im David, what year is the pathfinder?
im going to find you a actuator recal procedure to see if that will take care of the problem
there is no reset procedure for the vehicle. while sitting in the vehicle with the key on. move the temp control from hot to cold and back to hot. can you hear the actuator moving full travel?
an actuator motor running. full travel should take a few seconds
inside the cabin. with the key on. not started.
they need to recalibrate the the actuators.
is it at the shop? they should know how to do that
what engine is in that? 3.3?
check the reference voltage and ground to the iac first. no sense replacing a part if the wiring is the issue
as far as re calibrating the actuator for the hvac system, there is no procedure.
they will need to access the actuator to see what its physically doing. and then try to reposition the flap to match the actuator position
they are lazy and dont want to access it.
if it worked ok before, then absolutely.
i have to get out of this shop. ill be back on in about an hour we will continue
the temp mix actuator can be accessed through the glove box. it will need to be removed and you should be able to see the actuator.
checking in to see how its going
ok. good luck
it only makes sense that the controller could be bad. if its bad then it wont allow communication with the computer either.
anything is possible, but i dont believe that that could be proven
every computer, module, programmer, processor in the vehicle interface with the main computer one time or another.
you're welcome. if you were satisfied with my assistance, please accept the answer and leave a 5 star rating for me. thank you. have a great day.
i second that ...........
the iac and hvac dont have anything to do with each other, and its just possible the other shop has no idea what they are doing. the hvac normally doesnt turn on the check engine light as it has its own fault memory. which can be obtain through a self diagnostic on the climate control panel
its possible the iac will still fault. but wait til after the controller is replaced. you can find one on ebay.
thank you for the rating. i truly appreciate it
part number for the processor?
that second part number isnt showing up anywhere.
Nissan Auto Climate Control Diagnostic:To run a self-diagnostic for the DCC:Turn engine on. Within 10 second of starting engine, press and hold ‘OFF’ button on the DCC for 5-10 seconds until all segments on the display light up.Test 1- Display Test. Look for any missing segments or iconsPress Up arrow to get to Test 2.Test 2 – Input signals from each sensor Wait a couple seconds and it’ll display error codes (20=all ok, 21=ambient, 22=in-vehicle, 24=intake, 25=sunload (test in sunlight to prevent this error), 26=PBR)Press Up arrow to get to Test 3 or Down arrow to get to Test 1Test 3 – Mode Door Motor This test takes a little longer. 30=all modes ok, 31=vent, 32=B/L, 33=B/L, 34=Foot/Def 1, 35=Foot/Def 2, 36=DefPress Up arrow to get to Test 4 or Down arrow to get to Test 3Test 4 – Actuators Test Pattern Toggle modes 41-46 by pressing defrost button on ACC.Test 5 – Temperature Readings Press defrost button to toggle through sensors (ambient, in-vehicle, intake in that order). If the temp is -22, then that sensor is not working. The temperature can also be adjusted to compensate for differences between temp setting and the temp felt by driver. It can be adjusted 6 degrees up or down. While in Test 5, press the fan switch and then the temp adjustment can be made using the Up/Down arrows.Hit Auto button or turn car off to exit self-diag.
ill check back with you in a little while gotta do some running
