atc has codes of 36 26 25 35
is code 36 causing the other ones
problem is not real good heat coming from vents. the only
thing not new is heater core

 

in the owners manual it shows the control head with lights just to the right of the defrost switches. the one in the car does not have lights by the switches lights up on the face.
has some one replaced it with a different one. and that is why i have codes ?????? not the right control head ????

 

took the unit out . took the whole thing apart. the vent for the sensor was full of lint hair dust etc. cleaned it all out dusted it clean with a dash vent brush soft one . put all back together . left neg cable off for twenty min hooked all back up no codes now so far. knock on wood will see what happens and let you know.

 

still working great no codes
