what's up guys,

used to own a 2000 sierra and I remember never having to ALWAYS press the recirc button when i started up my truck. Now I have an '09 silverado and have to do this every time i get in the vehicle. I hate it b/c lets say im at a gas station and i start up, fumes directly sucked up into the cab!

Is there a way to take the a/c recirculation switch and bypass the relay to have it always in the on mode like past models?

thanks!
