help!!!

my blower fan is not working at all from my control panel. i tested the fan it is functioning, i checked all the fuses and relay and they are fine, so i replaced the blower motor control module and it still does not work. can anyone help me figure this out is there something i am missing. thanks in advance

Did you replace the control panel itself? Have you disco'd the battery long enough to reset everything?

 

[highrollin113]

no and no, the control appears to work all the functions work on the screen anyway so i just assumed its still good, and i am going to try disconnecting the battery now and trying that

Did you check the 40A fuse in the top row of fuse panel under hood? Somehow I missed that one. Mine blew when the fan module failed. Did you have to 're-wire the connections on the new module? Apparently they are on the third 're-engineer of this part.

By control module do you mean blower motor resistor? Very common on our year trucks.

There are two different setups in those trucks. A blower resistor module which has a heat sink and a blower resistor with the exposed circuit.

so the 40amp fuse was blown, i was estatic to think simple fix but after replacing that still does not work!

i replaced the module with the fins on it

i disconnected the battery that didnt do anything

while driving i get air movement through the vents i changed all the setting(defrost, vent and floor) all worked and i adjusted the heat and that worked too just no fan turning on to push the air

i am more lost than ever, i am going to try putting the old module back in hoping that the one i bought was faulty and that the fuse was the problem but i know that wont be the case i am just hopeful, can anyone think of anything else

thanks

Is your 30A Heater/AC fuse in the driver side fuse panel good?

yes all the fuses are good

Great news!!!! it works again, i pulled the controls out and when i put them back on i saw them reset, i guess its called logic lock, so once it reset the fan started blowing

THANKS for all the help and suggestions!
