i have an 05 chevy trailblazer that after you clear codes drive it acouple days this code comes back. i have read lots of info on blower and checkvalve the blower does not come on when u turn on the key or start engine.it will run fine if u short across relay mounted beside it.this relay gets battery+ on activater circuit when key is turned on.question is where does it get battery- to turn on relay.is it supposed to come on with the key or at engine start-up.the info. i have seen so far leads me to believe it should blow at start-up.am i right for looking at this or should i go back to check-valve
