check your fuses first if they are ok then check for power and ground at your blower motor connector also scan test for codes
I check all of the fuses and all ok. Somebody told me to check bus bar which I don't know where that would be. Where would the ground be for the blower motor be I found the one by the fuse box under the hook and everything look good there Thanks for your help
