after testing the BROWN / YELLOW wire & IF there is NO Voltage, test Fuse 13 & 116, located in the CJB, for Voltage + on "both sides" of each fuse
let me know what you find

thanks

But there is power cause blower will start and work fine until engine shuts off than you restart engine and no blower

I've checked #13 but not the one in engine but still if they were blown blower would never start.

Ok I thought there was an updated ground for the blower motor but not on this model year.So just to clarify the blower works on all speeds when it does work? This is an Electronic climate control system ? when you cycle the key off it wont operate again? Do you have both power and ground to the blower motor connector when the blower fan is inop?

Customer: replied 1 year ago.
I changed blower n resistor all lights light up on climate control I set it on auto n nothing I set blower on full speed nothing however I turn rear ac and it works fine after a few cycles of turning ignition on n off all of a sudden front ac turns on works fine I can lower fan speed n it works. I shut car off restart again all displays on but no ac but rear works fine.
Expert:  HDGene replied 1 year ago.

Right, but what you need to verify is when the blower does not work is if it is still getting power and ground on high speed. If it has battery voltage and ground the fan should run, when you put it to lower speeds the blower resistor drops the voltage to lower the fan speed. it could be an issue with the blower switch or possibly a defective new part. Just because it is new means its a good part. thats why its important to check the circuit when it is inoperable

I will work on it this Saturday n will check voltage on high speed to see what I'm getting and let you know then is that ok?
Expert:  HDGene replied 1 year ago.

Yes thats not a problem. just let me know what you find and we can double check everything from there
