05 tahoe. My rear ac blows but my front only blows when I am moving. My controls light up but that's it. My defrosts doesn't work either. I have 54000 miles on it an no warranty. Please help

 

the blower motor might be out. your getting air due to the forced air caused by you tahoe moving and forcing the dampers open in the front. not too sure but there might be a relay or a possible feuse that is blown as well
