my pac 2004, a/c front blower not working the rear blower is good

 

blower motor resistor under pass side dash

 

chrysler tech is this the one that the call it power module// thanks anyway

 

yes if u have ATC or auto temp control yes its a power module

 

chrysler tech ,I check all the wires from the module 1 wire w/c is LT BLUE coming from the ATC crtl no power (no juice)
at all. so I think the problem is from the control. thank s for your help!

chrysler tech, thank you so much for your attachment. by the way I look at the drawing, from ATC wire to power module ther is no power . so they I look at it the problem will be the ATC, b/c all the fuses& relays are OK. I will ask you about this ATC, where is it located.

 

its the ac control head the thing u use to change the temp and fan speed. Look at the diagram again if u dont have ne power U mean to control the fan or to run the fan? That DB/LB wire all it does is send amux signal to the module and then it goes from there. The fan itself is just an output of the module. There is a main fuse 40 amp that gives the module all its power. All of the times I have run into this its been the module but if u want to spend ooo 400 or so and take a guess its the control head be my guest.

 

it's fix already thanks to chrysler tech good job

 

what was it ne way the module?
