No AC or Heat blowing took blower motor out of car tested it to see if it still works and it does when I put power to it but doesn’t when I put back in car checked fuses nothing blown. ECTU has power but not sure if still fuctioning properly need to know what to change to get air to come back on was working only on high setting but went out completely after I put new battery in after it came back from shop got fuel pump fixed has not worked since. Will not put in shop will do work on it myself just need to know what to change thank you


I am assuming that your car has auto a/c controls. If so the following link should help. It is the most common cause of a no blower condition on those cars.
